Citation | Distinguished for his work in applied and computational mathematics with especial reference to aeronautical engineering. He has significant research contributions in the study of unsteady and three-dimensional boundary layers, in vortex dynamics including vortex breakdown, and in the computation of nonlinear inviscid transonic flows. His current work is on Navier-Stokes solvers including turbulent models. In the last two decades computational fluid dynamics has been developed very strongly, and includes important advances in the computation of inviscid transonic flows. Dr. Hall has been in the forefront of this activity and his multigrid Euler equation solver is thought to be one of the very best available, if not the best. As one of the leaders in computational fluid dynamics, Dr. Hall shows also a keen appreciation of the practical consequences for aeronautical design of results obtained by numerical computation. |
