A Simple, Robust and Fast Algorithm to Compute Deformations of Multi-Block Structured Grids

A grid deformation method has been developed for the movement of multiblock, structured grids due to surface deformation arising from aeroelastics or design optimisation. The method uses a volume spline interpolation technique to compute the deformation of block vertices and block edges. After that, the deformation of block-faces is computed by...

Computations of three-dimensional unsteady supersonic cavity flow to study the effect of different downstream geometries

Computations of three-dimensional unsteady supersonic cavity flow are performed for a freestream Mach number of 1.2. Two cavity geometries are considered: (i) a simple rectangular cavity of length-to-depth (L/D) and length-to-width (L/W) ratios of 4.5, and (ii) a cavity with a 45° ramp attached to the downstream wall of the simple rectangular...

Leading edge vortex flow computations and comparison with DNW-HST wind tunnel data

Computations are presented for the vortical flow around a sharp-edged cropped delta wing with 65° leading edge sweep using a computational method based on the Reynolds-averaged Navier-Stokes equations. It is demonstrated that turbulence modelling plays a crucial role in the ability to capture the vortical structures. Standard one- and two...
