Abstract

Abstract: Heat exchanger is a kind of highly important equipment in chemical field. It has been widely used in chemical, petroleum, food and other industries. In this paper, fluent 17.0 software is used to numerically simulate the heat exchanger performance at different baffle-plate spacing. The results show that, within the range of 100 to 300 mm baffle-plate spacing, the "flow dead zone" area increases and the pressure drop decreases with the increase of baffle-plate spacing; and the convection heat transfer coefficient presents a downward trend, while the convection heat transfer coefficient per unit pressure drop, the convection heat transfer coefficient per unit pump power, and JF factor increase gradually. The conclusions of the above study can provide a basis for the trends in the actual engineering of heat exchangers.

Key words: heat exchanger, baffle-plate, spacing, numerical simulation, performance analysis
