John Steinhoff is a classical physicist, best known for his important contributions to computational fluid dynamics
Computational fluid dynamics
Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with...

Most of his research has been involved the treatment of vortex-dominated flows in computational fluid dynamics and the treatment of short wave equation pulses, including the solution of real problems of engineering importance.The recent development of the vorticity confinement method that eliminates effects of numerical diffusion, for computations on Eulerian grids, without the use of Lagrangian markers. This technique has recently been used in many applications involving computation of: Helicopter Blade—Vortex Interaction, Delta Wing Flow, Helicopter Rotor/Body Flow, Helicopter Body—Vortex Interaction, Dynamic Stall, Aircraft Trailing Vortices, Supersonic Flow Over Missiles. John also developed another computational technique, wave confinement, for propagating short wave equation pulses over long distances without the use of Lagrangian markers, which require the use of complex logic
