TY - JOUR TI - Effect of liquid phase compressibility on modeling of gas-liquid two-phase flows using two-fluid model AU - Shokri Vahid AU - Esmaeili Kazem JN - Thermal Science PY - 2019 VL - 23 IS - 5 SP - 3003 EP - 3013 PT - Article AB - In this paper, a numerical study is performed in order to investigate the effect of the liquid phase compressibility two-fluid model. The two-fluid model is solved by using conservative shock capturing method. At the first, the two-fluid model is applied by assuming that the liquid phase is incompressible, then it is assumed that in three cases called water faucet case, large relative velocity shock pipe case, and Toumi’s shock pipe case, the liquid phase is compressible. Numerical results indicate that, if an intense pressure gradient is governed on the fluid-flow, single-pressure two-fluid model by assuming liquid phase incompressibility predicts the flow variables in the solution field more accurate than single-pressure two-fluid model by assuming liquid phase compressibility.
