CFD Modeling of Shell-and-tube Heat Exchanger Header for Uniform Distribution among Tubes
Several types of different header designs were numerically studied to have uniform distribution of gas phase flow in the header of the shell-and-tube heat exchanger. The different geometries included the inlet nozzle position into the header, inlet nozzle shape and the length of header. In the numerical calculation, standard k-epsilon turbulent model was employed. In this study, standard deviation was used to evaluate the uniformity of the flow distribution among the whole outlets of the header. As results, flow regime in the header can be visualized using post-processing of numerical results. Furthermore, the velocity distribution can be able to improve by changing from vertical to horizontal-vertical (down) of header.
