Численное моделирование тепловых и газодинамических процессов теплообменных аппаратов с перфорированными ребрами спирального типа

Abstract

Heat exchangers play a key role in many industrial systems where increasing thermal efficiency with minimal pressure loss remains one of the main tasks, especially for compact heat exchangers (KTO) operating in conditions of limited space and high operational requirements. In recent years, spiral fins have attracted attention due to their ability to create swirling flows that promote fluid mixing and heat transfer intensification. However, a simple inversion of the spiral direction (RSF) often leads to significant pressure losses without a commensurate increase in heat transfer, which limits the practical application of such structures.
