The design of uniform tube flow rates for Z-type compact parallel flow heat exchangers

Additionally, the results reveal that if constraints are placed on both the desired system non-uniformity and the inlet gage pressure, different initial guesses of the design variables will yield almost the same design for the heat exchanger. The sensitivity analysis technique is then used to reduce the number of design variables and to shorten the computational time. The results indicate that an acceptable design with nearly uniform tube flow rates for Z-type compact parallel flow heat exchangers can be obtained using sensitivity analysis, saving 41% of computational time.
