新型螺旋管气液分离器分离性能数值模拟
摘要
Abstract
Adopting computational fluid dynamics method, selecting two-fluid model and RNG k-∈ turbulence model, the new non-holed spiral pipe is numerically simulated to predict its gas-liquid separation performance. The influence on gas-liquid separation of the spiral caused by the structural parameters of pitch and pipe diameter, and the operating parameters of liquid density, liquid viscosity, inlet velocity and gas void fraction are analyzed respectively. The results show that the separation effect can be improved by increasing the pitch, liquid density, or inlet velocity within a certain range. The separation effect is improved with the decreasing of pipe diameter when the inlet velocity is relatively high. On the contrary, the separation effect is improved with the increasing of pipe diameter when the inlet velocity is low. The decrease of liquid viscosity is favorable to the separation effect. These conclusions can be guidance for the subsequent hole drilling, separation experiment verification and practical engineering application.关键词
