Coupled algorithm cfd
WebDefinition of CFD Computational fluid dynamics (CFD) is a technique of flow predictions by numerically solving governing equations of fluid flows. Governing equations are conservation of mass, momentum, heat and mass transfer. Numerical methods are used to convert partial differential equations in to algebraic set of equations. WebPressure-based algorithms for the pressure-velocity coupling were adopted for compressible and incompressible flows with a series of new implicit developments specific for turbomachinery (mixing plane, boundary conditions, treatment of source terms), to improve convergence speed and robustness.
