| Abstract: | Numerical simulation of heat transfer on the shell side in water cooler was carried out by use of commercial code Fluent.Based on the simplied mode,streamlines and tempreture contours around helical coil were described in detail with some specified coil sizes.The effect of cooling water and helical structure on heat transfer near water side had been analyzed.In order to get simplified heat transfer equation around helical coil,the data obtained from simulation was nolinearly fitted by use of software DataFi... |
