The realization that science enables mankind to question rather than accept; naturally drew me towards this subject. Whilst applying for college, I took the decision to study Mechanical Engineering hoping it would provide a constant sense of discovery, besides laying the foundation for all other engineering fields. I believe it holds great depth and opportunities for never-ending investigation; paving the way for me to build a deeper desire to study it at an advanced level. Given the opportunity, I look forward to feeding my curiosity and discovering more at the University of Florida.
I joined SSN College of Engineering with a partial tuition waiver that was awarded in recognition of my high school grades and for my accomplishments in the field of sports. The initial years of my program exposed me to an eclectic mix of subjects not limited to courses in computer programming, manufacturing, material science and mechanics. Over the course of time, I started to build a latent interest in myself for thermodynamics. Its wide range of application and the influence of its laws over every scientific discipline including biological and interstellar system had an exhilarating effect on me.
During sophomore year, I submitted a project proposal to design and fabricate a bubble pump operating in a slug flow regime; and received a grant from the SSN Research Center. Working as a team, we were able to effectively improve the efficiency of the pump operating under varying conditions. While this further enhanced my understanding of two phase flow models, I hope to extend upon my knowledge in this topic using the advanced facilities at the Boiling Heat Transfer and Clean Biomass Energy Research Lab.

I am presently involved in a project on latent thermal energy storage, wherein the performance of a horizontal tube in tube heat exchanger charged with multiple pins on the shell side is being investigated numerically. An alternate thermal resistance method has been adopted to model the storage system. Besides completing the project successfully, I wish to publish the results of my study by the end of the academic year.
Research requires discipline, dedication and hard work; I believe my academic record and training have confirmed that I possess these qualities. My love for science and mathematics has taught me to be logical in my thinking and precise in my actions, culminating in my decision to apply for Master’s program at University of Florida.

As a result of the design parameters from the experimental column, the following design is proposed: the column will run at a vapor velocity of 4.85 ft/hr and will have a HETP of 4.30 inches. This will result in a packing height of 38.7 feet. The reboiler will have an area of 113.52 ft2 and the area of the condenser will have a value of 45.54 ft2 in which heat exchange will take place.
Refrigeration, the production of cold, is an essential practice for present-day living. It is used in a many place like the processing and preservation of food, conditioning of air for comfort, manufacture of chemicals and other materials, cooling of concrete, medical applications etc. Refrigeration is defined as the science of maintaining the temperature of a particular space lower than its surrounding space. Refrigeration and air conditioning involves various processes such as compression, expansion, cooling, heating, humidification, de-humidification, air purification, air distribution etc. In all these processes, there is an exchange of mass, momentum and energy. All these exchanges are subject to certain fundamental laws. Hence to understand and analyses the refrigeration and air conditioning systems, a basic knowledge of the laws of thermodynamics, fluid mechanics and heat transfer is essential.
Latent heat thermal storage is an alternative to the sensible heat system. This system operates by making use of the ability of the material to store energy through its ability to phase change from solid to liquid or liquid to solid. (Sharma, Tyagi, Chen, & Buddhi, 2009). The process relies on the chemical properties of the chosen material where heat is absorbed or release as the material undergoes a phase change from solid to liquid or vice versa. (Sharma, Tyagi, Chen, & Buddhi, 2009). The process starts when the temperature reaches the required temperature-phase change temperature- and stays constant until the whole process change is finished. Most of the latent heat thermal storage systems are currently based on solid to liquid transition.
Since my youth, my curiosity correlated with my scientific endeavours. My biggest academic interests are Science and Mathematics, because the complexity of concepts intrigue and challenge me. I ask numerous questions, aiming to completely grasp notions, both on class material and on extra research done independently. Problem-solving always lit a spark in me: where most would abandon, I utilize my creativity to push forwards. Chemistry and Physics are omnipresent in everyday life,
When analyzing the thermal-hydraulics of two-phase flow, it is expressed in terms of macroscopic field equations and constitutive relations using a continuous formulation. This has been incorporated in classic formulations including the homogeneous flow model, drift flux model (Zuber and Findley, 1965), and the two-fluid model (Ishii, 1975). The formulation considered the most accurate is the two-fluid model developed by Ishii due to its treatment of the interfacial interaction terms. It considers the phases separately in terms of two sets of equations that govern the mass, momentum and energy. These equations represent the macroscopic field of each phase, and are not independent of each other but have phase interaction terms that couple the transp...

We have reached a point in time where the antediluvian ways have either been completely forgotten or are simply ignored for loss of necessity. This fast progressing world owes everything to the researchers and innovators responsible for the ever changing paradigm of technology. My capability as an engineer, however, to be truly able to understand how the various design aspects behind each innovation, helping me ponder over the numerous ways in which it can be implemented for technological betterment is what makes me stand apart. Right from my childhood, I have been fascinated by bicycles, motorcycles, cars, mechanical structures and basically anything that had virile relations; this was mainly because of the automobiles and other vehicles in movies that always used to drum in a sense of amazement that used to reverberate in my memories long after. It was only a matter of time before I came to realize the sheer brilliance behind every design, the immense perfection engineers strive to achieve and the amount of hard work and dedication required to impeccable levels in the whole process. I wanted to be a part of it and it was then that I decided what was worth doing with my life. I chose Mechanical Engineering as my major in my Undergraduate study and frankly, the field never ceases to amaze me.

Remaining methane and hydrogen are separated in reflux drum where the vapor stream is combined with other gases streams. The overhead of first and second separator are combined to form fuel gas. The liquid stream exiting in the bottoms of the reflux drum is pumped at pressure of 3.3 bar for discharging pressure. The pump stream is separated in two streams. One stream is to feed to tray one of the column and the other one stream is cooled down to 38 0C in heat exchanger. Then, the cooled product stream is sent to storage.
In experimental analysis result was completed and the effect on temperature reduction and the pressure drop in the finned tube and shell side was observed. In present the heat transfer rate and efficiency is low by using finned tube. Compare both existing and new model type heat exchanger over all heat transfer rate is increased and also the efficiency of the heat exchanger for semi circle fins is increase d by 3%, and for hexagonal fins is increased by 6% of finned tube heat exchanger. So the hexagonal fin is used than the semicircle

Suction and lift are paramount contemplations when pumping liquids. Suction is the vertical separation between the liquid to be pumped and the core of the pump, while lift is the vertical separation between the pump and the conveyance point. The profundity from which a hand pump will suck is restricted by air weight to a working profundity of less than 7 meters. The depth to which a hand pump will lift is administered by the capacity of the pump and the driver to lift the weight in t...
