By way of solving a three-dimensional viscous and compressible Reynolds Navier-Stokes equation, a numerical simulation on the three-dimensional turbulent flow was carried out in the gas turbine cascade for turbo-charger set of marine supercharged boiler. The simulation has been accomplished through the adoption of a full three-dimensional numerical simulation technique and "mixing plane"...
The tubular pump device model including rotor, stator and inlet and outlet passages was simulated based on SIMPLEC arithmetic and standard k-?? RNG turbulence model. The match of rotor and stator in tubular pump was optimized. The numerical results show that the device model has a steady flow field and high efficiency when the distance between rotor and stator is 0.11D2. With the distance increasing...
Based on CFD technology, the three-dimension transient numerical simulation of single-phase turbulence flow in the hydraulic retarder was performed by sliding mesh theory with using the standard k-?? turbulence model and the SIMPLEC algorithm simutaneously. Through the numerical calculation, the internal characteristics of velocity and pressure distribution were analyzed The braking torque was also...
