A Fully Integrated Approach to Component Zooming Using Computational Fluid Dynamics

Abstract: This study focuses on a simulation strategy that will allow the performance characteristics of an isolated gas turbine engine component, resolved from a detailed, high-fidelity analysis, to be transferred to an engine system analysis carried out at a lower level of resolution. This work will enable component-level, complex physical processes to be captured and analyzed in the context of the whole engine performance, at an affordable computing resource and time. The technique described in this paper utilizes an… Show more

“…The main focus has been on improving the three key parameters of powerplant performance; thermal efficiency, specific power and emissions [2][3][4][5]. While the basic measure of performance is thermal efficiency, there is an increasing need to extract more power from smaller powerplants [4,[6][7][8]. Various options for increasing efficiency and power while reducing emissions are under investigation, for instance with water injection [9,10].…”

“…5 The analysis of aerodynamic performance can be studied by several methods, including Conformal Mapping, 6 Thin Airfoil Theory, 7 Surface Panel Method, 8 or computational fluid dynamics (CFD) solutions. 9,10 The working airflow moves over an airfoil along the surface curves, rather than Cartesian coordinates. When the boundary layer equations are written in curvilinear coordinates, the equations show that local pressure on an airfoil surface has a strong dependence on local radius of curvature.…”

“…For example, one can couple an engine performance simulation program written in Delphi for an average PC with a nozzle CFD model developed in FORTRAN for multiprocessor workstations. Such a research trend has also been followed with similar activities at Cranfield University by Pachidis et al [16] .…”
