Characteristic Analysis of the Influence of Flow Rate Distribution in Each Flat Tube of Parallel Flow Heat Exchanger to Heat Transfer

Article Preview

Abstract:

In this paper, the heat transfer rate of parallel flow heat exchanger was obtained in the condition of non-uniform flow distribution by 3D numerical simulation. The maximum theoretical heat transfer rate of parallel flow heat exchanger was obtained through 1D calculation. Ultimately, the correlation of the influence of non-uniform flow distribution on heat transfer efficiency was obtained by the comparative analysis of non-uniform flow distribution and heat transfer efficiency and regression calculation. It was found that the forecasted heat transfer efficiency error of correlation was within 2%.
