One of the simplest and applicable heat exchangers is double pipe heat exchanger (DPHE). This kind of heat exchanger is widely used in chemical, food, oil and gas industries. Upon having a relatively small diameter, many precise researches have also hold firmly the belief that this type of heat exchanger is used in high-pressure applications. They are also of great importance where a wide range of temperature is needed. It is also well documented that this kind of heat exchanger makes a significant contribution to pasteurizing, reheating, preheating, digester heating and effluent heating processes. Many of small industries also use DPHEs due to their low cost of design and maintenance. The aim of present paper is to review “The various Nano fluids which affect the heat transfer rate with structural modification of double pipe heat exchanger.” on the basis of previous study

Heat exchanger, nano fluids, DPHE, heat transfer rate etc.
