Numerical and Experimental Analysis of Shell and Tube Heat Exchanger with Round and Hexagonal Tubes

Shell and tube heat exchangers are used to transfer thermal energy from one medium another for regulating fluid temperatures in the processing pasteurizing industries. Enhancement of a rate is desired maximize efficiency shell exchangers. In this research work, we performed computational dynamics (CFD) simulations experimental analysis on using round hexagonal tubes range flow velocities both parallel counter arrangements. present transfer, temperature drop, coefficient computed three turbulence models: Spalart–Allmaras, k-epsilon (RNG), k-omega shear stress transport (SST). We further utilized logarithmic mean difference (LMTD) method compute mass rates Our results show that increased by introducing structure tubes, since it has better disruption as compared tubes. validated our simulation with experiments. For more accurate results, CFD deduced directly depends upon velocity fluids number turns tube.
