Abstract
In this thesis, the numerical solution of navier stockes equations and turbulent equations have also been investigated in fluent software, to investigate baffle type change from cut off to helical in shell and tube heat exchanger. RNG K-ε turbulence model was used to perturbations modelling. The main objective of baffle changing in thesis is increasing propane temperature in pipes outlet. 4 heat exchanger type with different helical angles (35, 40, 45 and 50) compared with simple baffle type. Studies indicate that heat exchanger with helical angle of 50°, maximum outlet temperature of propane will result and have the maximum heat transfer rate in shell. Exchangers with helical angle of 40 degrees have the highest ratio h / Δp, which reflects the heat transfer rate to pressure drop ratio.
