Lahare, Pushpendra Bahadur Singh (2016) Analysis of Rectangular Channel Printed Circuit Heat Exchanger(PCHE). MTech thesis.



Cryogenic heat exchanger used for conversion of energy of one fluid to another as here Printed Circuit Heat Exchanger (PCHE) used as compact heat exchanger of very small hydraulic diameter as compared to its length, due to small hydraulic diameter of long length flow becomes completely developed with laminar in nature results higher in effectiveness and less axial conduction loss due to its design. Mass flow distribution and thermal analysis in four layer channels by using the design of inlet header location and distributor path for both hot and cold fluid in counter flow direction at different Reynolds number range (100<Re<600). In thermal analysis calculation of Temperature, Pressure variations, Nusselt number, Colburn factor and Fanning friction factor in different channels has been checked, also performed double channel Printed Circuit Heat Exchanger model of rectangular cross-section using helium as a fluid at Re 100 to validate the ineffectiveness.The performance accuracy of above practice checked by using simulation software Ansys Fluent and fabrication is done using SolidWorks.
