STUDY THE EFFECT OF PIPE GEOMETRY ON PRESSURE DROP FOR AIR-WATER TWO-PHASE FLOW

Abstract

This plan aims to examine the pressure drop in flattened copper passageways. The fluid mechanics part of the project is the subject of this article review (pressure drop and void fraction). The aim of this research is to examine the benefits and drawbacks of Two phase flow in copper passageways with a low channel height.  These passageways' possible benefits include decreased refrigerant charge, and five various channel structures are being looked at.  The tubes that have been utilized are smooth tubes. The tubes are then compressed to heights of 9.0 mm, 8.8 mm, 6.0 mm, and 5.0 mm, in that order. This calculation is taken from the inside of the vent. The pressure drop increased as the tube's height declined, and it also increased with rising total volume flow rate or raising water flow rate with steady total volume flow rate, according to the findings. The findings were also compared to the Lockhart-Martinelli prediction correlation, which showed a strong agreement.
