摘      要：This paper presents a numerical emulation study of heat transmission through tube banks in *** configuration is displayed by fluid dynamics using computer programs(CFD)software(ANSYS fluent).The computer model is used to predict the values of the Nusselt number when changing the values of heat flux and longitudinal *** longitudinal pitch(SL/D)of 1.3,1.8,and 2.4 *** transverse pitch(ST/D)of 1.5 mm,and also considered Reynolds numbers 10000,13000,17000,and *** staggered configuration of the tube bundle is demonstrated to investigate the impact of this arrangement on the heat transmission rate from the *** gotten results indicate that the rate of heat transmission increases with decreases in the longitudinal spacing(SL).As the longitudinal spacing(SL)increases to about 44%the Nusselt number is slightly decreased by about 9%.The coefficient of heat transmission,Nusselt number,and the heat transmission data obtained from(CFD)Compared to previous research results,there is a decent agreement originating after comparison.
