Brian Spalding

Dudley Brian Spalding, FRS FREng (born 9 January 1923) was Professor of Heat Transfer and Head of the Computational Fluid Dynamics Unit at Imperial College, London. He is one of the founders of, and influential persons in, the development of computational fluid dynamics (CFD). In 1983, he became a Fellow of the Royal Society.

Professor Spalding was born at New Malden, Surrey, England. He received his BA degree in Engineering Science from Oxford University in 1944 and PhD from Cambridge University in 1952. He is the founder of the company Concentration Heat And Momentum Limited, (CHAM) specialising in computational fluid dynamics and heat transfer processes. CHAM's major product is the widely used PHOENICS CFD code. Professor Spalding himself is the main creator of, and contributor to, PHOENICS.

Together with his student Suhas Patankar he has developed the SIMPLE algorithm, a widely used numerical procedure to solve the Navier-Stokes equations.

CHAM

Professor Spalding formed Concentration Heat and Momentum (CHAM) Limited in 1974. From the outset commercial CFD services were provided to industrial and governmental clients based on the pioneering technology that had emerged from his research group at Imperial College in the late 1960s. Later these services were based on PHOENICS, the first commercially available Computational Fluid Dynamics Software, which he created and released in 1980.
