Load Flow Analysis is one of the most common computational procedures used in power system analysis. The load flow problem can be defined as: Given the load power consumption at all buses of a known electric power system configuration and the power generation at each generator, find the power flow in each line and transformer of the interconnecting network and the voltage magnitude and phase angle at each bus. Analysing the solution of this problem for numerous conditions helps to ensure that the
affects the mixed product quality, rate of reaction of the reactor etc. It is well known that the viscosity of the fluid is the key factor of the flow behaviour of non-Newtonian fluid (Tanguy et al., 2006). The non-Newtonian fluid viscosity is closely related to the applied torque on the impeller. If viscosity of the non-Newtonian fluid is very high (flow index tends to zero), the required torque for achieving the satisfactory mixing becomes also very high and this leads to destruction of mixing system
Magnetohydrodynamics (MHD) is the study of the interaction between magnetic fields and moving conducting fluids. The idea of magnetohydrodynamics phenomenon was first conceived by Michael Faraday in the year 1832 in his Backerian Lecture to the Royal society. In Great Britain he did an experiment at the waterloo Bridge for measuring the current from the flow of the river Thamus in earth’s magnetic field. This experiment in a way outlined the basic idea behind MHD generation over the years after that
tribulations allied with river and its flow. With increase in utilization of water resources; flow in river channels are gaining significant importance among the research scholars. More and more complicated problems are encountered due to multipurpose use of alluvial rivers. Flow velocity, Shear stress, and Unit Stream Power are important characteristics for the measurement of the behavior of the river. Quantification of flow velocity, shear stress, and Unit Stream Power is important both for engineering

will produce more efficient power production. Bare wind turbine may good but it will better if adding this element. Wind behaviour is not constantly in high speed and frequent therefore shroud purposes is to collect wind speed and focus it to the blades of wind turbine. 2.5.2 Study of Shroud Design 5.2.3 Comparison of Bare and Shrouded Turbine This study of shroud determined by comparison of bare and shrouded turbine. The initial diffuser model used in our previous study is of 120mm length with L/D
accurate at certain flow rates, or they might not be valid at all, and it might be necessary to recalibrate the specifications for higher viscosity liquids. The purpose of this experiment is to examine the performance and characteristics of a centrifugal pump, its motor, and the corresponding piping system, used to pump an ethylene glycol solution. The pump used in this experiment has a performance curve based on water, so pump performance curves, as well
Rheological behaviour of most of the fruit juices can be normally described by a power law relationship. However, the rheological behaviour of orange juices has been extensively determined the power law, Herschel-Bulkley being the most used (Ibarz et al., 1994), while that of clarified AJ has been described as Newtonian (Ibarz et al., 1987). Šimunek et al. (2014) reported the influence of high power ultrasound on changes in rheological parameters of ultrasound treated apple, cranberry, blueberry
I always had a doubt in my mind why only two energies we are talking about while transferring energy, why not three or more energies. And during my intermediate my teachers thought same, it’s created more interest towards mechanical engineering to study much on potential and kinetic energies responsible for transfer of energy from one place to other place through mechanical system. At the same time my mind also started thinking on electric and magnetic field energies, as days are passing chemistry
and engineering. Osmosis is a natural equilibrium process and forward osmosis is one of many types of osmosis processes. It works by having two solutions with different concentrations separated by a selectively permeable membrane and ‘pure’ water flows from less concentrated solution across the membrane to dilute the more concentrated solution, leaving the salts behind. The clue in the potential applications is widely used in nature, however only recently that its potential has begun to be recognised
< 1 shear-thinning (pseudo-plastics) These three types of power-law models are clarified butter in Figure. 2-2. Unfortunately, one of the evident disadvantages of the power-law model is that it fails to portray the viscosity of many non-Newtonian fluids in very low shear rate regions and very high. Viscosity for many suspensions and dilute polymer solutions becomes constant at a very high shear rate. This cannot be solved via the power-law model. (Kim,

1.1 Background of study A diffuser is a mechanical device that is designed to control the character of fluid at the entrance of a thermodynamic open system. It could be in the shape of round, rectangular and square. Diffusers are commonly used in heating, ventilation, and air-conditioning systems as a part of room air distribution subsystem, and serve several purposes as following, to deliver conditioned and ventilated air evenly, to distribute the flow of air in the desired directions, to create
paper deals with testing of power and torque coefficient of savonius rotor using numerical analysis. Numerical analysis least costly quick time response so that it is better than experimental method. Due to poor aerodynamic coefficient of savonius rotor, many people perform analysis. Some factor like as TSR, overlapping condition, geometry of rotor etc. affects the coefficient. Numerical method is very effective for testing of rotor geometry for extracting more power from wind. Numerical analysis
hold excess power to be evenly distributed when required during maximum and non-maximum peak hours. To address this issue, energy-storage devices, such as secondary batteries and hydrogen fuel cells have undergone research, testing, and eventual commercial use. Among these energy-storage devices is the Redox Flow Battery (RFB), a secondary battery with a simple but productive design. While commercialisation and design on a large-scale has been hit and miss for most systems, the Redox Flow Battery still
2.3 Power Flow Analysis 2.3.1 Introduction The power flow problem, or load flow problem, is the problem of determining the operating characteristics of a power system in steady-state [19, 36]. A power system usually has plenty of pathways, the power flow analysis technique is expected to compute the power flows over all the pathways and the voltage magnitude and angle at each bus with the help of a certain number of non-linear mathematical equations[10]. Besides the calculation of electrical
Valuation is one of the core concepts in finance, it is used to study market efficiency and answers the questions related to corporate governance. it is also used to evaluate different investment decisions. Valuation is the method of estimating the worth of an asset. Valuations can be done on company bonds and company investments which include shares, options etc Valuations and share prices forecasting has key position in finance as they represent one of the source for value perception of the

Introduction Thermodynamics is the study that shows the relevance between the work and the heat. Thermodynamics has 2 laws. The first law declares that the heat and the work are mutually interchangeable. The second law states that a entropy of a secluded regulation can never decrease, because the secluded regulation always develops toward the equilibrium thermodynamic. These two laws attitudinize the process of a heat engine.The first law is the implementation of the preservation of energy to the
