چکیده
|
A numerical and experimental investigation of flow and heat transfer in a gas- liquidthermosyphon heat exchanger the with built in heat pipes and aluminum plate fins for moderatereynolds numbers has been carried out. it's module is composed of 6 rows and 15 columns copperpipes with aluminum plate fins with dimensions of 130cm height, 47cm width and 20cm depth.the tubes have been filled with water with filling ratios of 30%, 50% and 70%. the density andthickness of fins are 300 fin/m and 0.4mm, respectively. the configuration of tubes is in-line with30mm pitch. this paper presents the distribution of temperature and thermal performance of theby using cfd modeling. a good comparison of the present cfd modeling results for the modelingthermosyphon heat exchanger with experimental results of hydrodynamic and thermal behavior is achieved
