Conjugate Heat Analysis on Trapezoidal Heat Exchanger for CO2 Refrigeration System

Present study focus on double pipe trapezoidal helical heat exchanger for CO2 refrigeration system by numerical analysis. By optimizing the velocity, the mode of study is conjugate heat analysis. Investigation is focussed onto getting desired output of temperature difference between inlet fluid and outlet fluid. When the flow is considered to be parallel, the inlet temperature of the fluid shows a decrement from 30 degree Celsius to 23.5 degree Celsius. Hence as per the analysis and studies, the new design shows a considerable difference in the inlet and outlet temperature and a considerable amount of heat transfer. The outlet temperature can also be varied by making variation in the geometrical design
