Summary on Grant Application Form |
Funds are requested for purchase of a cluster of distributed memory computers. Such clusters have recently become established for some CFD applications and offer a cost-effective alternative to the use of shared memory compute servers. This facility will be used for advanced CFD simulations with particular emphasis on turbomachinery internal air systems and seals. Recent experimental and computational research has shown that such flows are often intrinsically unsteady. Three dimensional, unsteady CFD calculations are now beginning to give new insights into the flow physics involved but require considerable computing power. For example, interaction of the internal air system with the unsteady flow between rotors and stators in the main gas path is important for turbine rim sealing. Preswirl chamber flows where cooling air from stationary nozzles is delivered to the cooling system in the rotor are also clearly unsteady, and buoyancy effects in high pressure compressor disc cavities are known to lead to 3D, unsteady flows. The new facility will enable larger, more realistic CFD simulations to be conducted.
