摘要: The objective of the present computational fluid dynamics analysis is an attempt to investigate effect length diameter ratio on fluid flow characteristics and energy separation phenomenon inside the Ranque-Hilsch vortex tube. In this numerical study, performance of tubes (RHVT), with ratios (L/D) 8, 9.3, 10.5, 20.2, 30.7 35 six straight nozzles was investigated. It includes generating better understanding effects stagnation point location RHVT. It found that best obtained when tube diameter 9.3 also fort case stagnation be farthest from inlet. results show closer distance hot end produced larger magnitude temperature difference. Computed good agreement published experimental results.
