Determination of the Convection Heat Transfer Coefficients for Multiphase Flow on Different Sections of a Closed Piping System

Abstract

The continuous demand for petroleum-based energy as well as the increased need for geothermal energy has led to higher demands of piping systems transporting multiphase flows at high pressures and temperatures. As a result, the research of multiphase heat transfer throughout the piping system is inevitable, much of which the intricate details are still unknown. Multiphase flows and heat transfer have been studied in a wide range of applications such as mechanical, chemical, nuclear, and mineral engineering. The data from this project should prove useful in industries all over the world, especially industries that deal with refrigeration and with piping oil. Also, engines are massively important and their efficiency is becoming more prominent than ever before, and this research could aid in their efficiency. Also, the longevity and performance of these multiphase-flow piping systems, amongst other things, depend greatly on the heat transfer rates they obtain. In this experiment, results were found showing the correlation between the orientation, input temperature, input air pressure, and flow rate of the liquid, with the flow rate showing to make the largest difference.
