Numerical Simulation of High-Temperature Gas Flow Rate Control Valve with Laval Structure by Fluid-thermal-structure Coupling
High-temperature gas flow rate control valve (GFRCV) with Laval structure is the core component of gas control system. The influence of fluid-thermal-structure (FTS) coupling deformations on the characteristics of GFRCV is a noteworthy issue. In this work, numerical simulations by two-way FTS coupling method and single computational fluid dynamics (CFD) method are conducted to analyze the velocity distribution, pressure distribution, deformations and flow characteristics of GFRCV with Laval structure. Variation regularities of velocity, pressure, and flow characteristics calculated by two-way FTS coupling method are more in line with the actual working conditions in consideration of the influence of FTS coupling deformations on flow characteristics, which reveals that two-way FTS coupling numerical calculations are more meaningful in engineering application.
