Chapter: 1 Introduction 1.1 Introduction to heat transfer In the simplest of terms, heat transfer is related with only two things: temperature and flow of heat. Temperature represents the amount of thermal energy available, whereas heat flow represents the movements of thermal energy from place to place. On a microscopic scale, thermal energy is related to the kinetic energy of molecules. The greater a material’s temperature the greater the thermal properties of its constituent molecules .It is natural for regions containing greater molecular kinetic energy to pass this energy to regions with less kinetic energy. It is materials properties which will lead to the heat transferred between two regions at differing temperatures. Examples…show more content…
• Copper diet supplements with efficient delivery characteristics. • High strength metals and alloys. • EMI shielding. • Heat sinks and highly thermal conductive materials. • Efficient catalyst for chemical reactions and for the synthesis of methanol and glycol. • As sintering additives and capacitor materials. • Conceptualization Generation of idea of how the performance of heat exchanger can be improved using the best effective methods and in most simple ways. Here heat transfer is most important thing which is main purpose of making a heat exchanger. • Identification of problem One of most influencing factor which reduces the performance and effectiveness of heat exchanger is heat transfer rate of heat exchanger. • Solution of problem Using nano particle with cold water is one pf the best method to improve performance of heat exchanger • Selection of heat exchanger Out of number of heat exchanger simple in design and least cost heat exchanger is selected in this phase • Design of heat
