Periodically Grooved Channel Pressure Drop Visualization Oscillatory Flow Heat Exchanger
概要:
抄録:
Ocean Thermal Energy Conversion (OTEC) usually uses plate type heat exchangers. For the improvements of OTEC efficiency, it is important to improve the heat exchanger efficiency. There are some methods for improving of plate type heat exchanger. As a typical method, there are the method of arranging grooves to a channel, and the method of giving the forced oscillation to a flow. By the former method, since a self-sustained oscillatory flow is generated in high Reynolds number, heat transfer enhancement is expectable. By the later method, since the resonance phenomenon appears between self and forced oscillations in the high Reynolds number flow, heat transfer is improved. However, few investigations were carried out for heat transfer enhancement on the low Reynolds number flow. Therefore, we carried out numerical calculations in grooved channel flow with forced oscillation at the low Reynolds number, and evaluated the influence of heat transfer enhancement and pressure drop. In addition, we carried out visualization experiments in the same model, and compared with the numerical solutions.
