The CPU power offered by the latest generation of supercomputers is such that the unsteady simulation of the full wheel of a compressor or turbine is now within reach. This CPU power is mainlyâ€¦ (More)

As computational methods attempt to simulate ever more complex physical systems the need to couple independently-developed numerical models and solvers arises. This often results from the requirementâ€¦ (More)

In the immersed boundary (IB) method, the surface of an object is reconstructed with forcing terms in the underlying flow field equations. The surface may split a computational cell removing theâ€¦ (More)

Recent LES suggested that the turbulence fluctuation in the wall-normal direction vâ€² plays an important role in the evolution of transition. This motivates the use of v âˆ’ f model for turbomachineryâ€¦ (More)

Reynolds-Averaged Navier-Stokes (RANS) methods have become an important design tool in aerospace industry. Turbulence models, which are required for closure of the RANS equations, are a substantialâ€¦ (More)

The efficiency of a turbine increases in general with an increase of the temperature of the working gas. In modern turbines this gas temperature may well exceed the melting temperature of the metalâ€¦ (More)

The objective of the Stanford ASC project is to develop a framework able to perform multi-disciplinary, integrated simulations on massively parallel platforms. 4 This paper focuses on theâ€¦ (More)
