co-authored a chapter; with Dr. DominiCue Pelletier;
for the “Handbook of Numerical Heat Transfer;

has served on advisory editorial boards for several ;ournals.
Roache was heavily involved in the movement to
establish ;ournal publication standards for . ; . .
His algorithm development contributions have included elliptic marching and semidirect
methods; domain decomposition; pseudospectral and multigrid methods; modified
method of characteristics; and solution adaptive and variational grid generation.
He and his staff at Ecodynamics were instrumental in performance assessments for
the - .S. Department of Energy;s Waste Isolation Pilot Plant. With Dr. Stanly Steinberg;
Roache contributed to symbolic manipulation use in CFD.
Roache;s pioneering development of the grid convergence index and the method
of manufactured solutions provided widely accepted standards for code verification
and solution verification; respectively. In “A Defense of Computational Physics; ;selfpublished;
2012;; he critiCued philosopher Karl Popper;s falsificationism—scientific
theories cannot be proved; they can only be falsified—removing this impediment to
practical model validation. Roache has been heavily involved in the . ; . committees
of ASME; the American Institute of Aeronautics and Astronautics ;AIAA; and
the American Society of Civil Engineers; and three . ; . workshops held in Lisbon;
