, Roe worked for the Royal Aircraft Establishment
from 1962 to 1984. Initially he worked in the field of missile aerodynamics and later shifted to CFD
and devised the Roe solver for numerical computation of compressible flow
s with shocks
. He published this work in the seminal paper titled "Approximate Riemann solvers, parameter vectors, and difference schemes" which appeared in the Journal of Computational Physics
in 1981. In 1984, Phil Roe left Royal Aircraft Establishment and joined Cranfield University
. Subsequently, in 1990 he moved to the University of Michigan
where he is a Professor of Aerospace Engineering.

in Ann Arbor. He is known for his work in the field of 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...

Magnetohydrodynamics
Magnetohydrodynamics is an academic discipline which studies the dynamics of electrically conducting fluids. Examples of such fluids include plasmas, liquid metals, and salt water or electrolytes...

Compressible flow
Compressible flow is the area of fluid mechanics that deals with fluids in which the fluid density varies significantly in response to a change in pressure. Compressibility effects are typically considered significant if the Mach number of the flow exceeds 0.3, or if the fluid undergoes very large...
s with shocks
Shock wave
A shock wave is a type of propagating disturbance. Like an ordinary wave, it carries energy and can propagate through a medium or in some cases in the absence of a material medium, through a field such as the electromagnetic field...
