A tribute to D.B. Spalding and his contributions in science and engineering

Abstract

Starting from early work on combustion, and his unique work in mass transfer theory, Spalding's unpublished ''unified theory" is described briefly. Subsequent to this, developments in algorithms by the Imperial College group led to the birth of modern computational fluid dynamics, including the well-known SIMPLE algorithm. Developments in combustion, multi-phase flow and turbulence modelling are also described. Finally, a number of academic and industrial applications of computational fluid dynamics and heat transfer applications considered in subsequent years are mentioned. Crown

Computational Aerodynamics: Solvers and Shape Optimization

“…[33]), was introduced in computational aerodynamics by Paullay and MacCormack [34] in 1972, and to-date, it remains the most widely used discrete scheme.…”

Thermodynamically consistent bi-velocity mass transport phenomenology

“…Following Spalding [20,21], the relations (11)-(15) are abbreviated as the volume continuity equations (the continuity equation of the volume density, VCE). This law permits the analysis of an arbitrary transport process in the systems where volume changes due to the diffusion are not negligible and consequently bi-velocity method must be considered.…”

“…The concept, sometimes called the drift-flux model, was adopted by researchers around the world as the basis for almost all finite-volume codes today. In the subsequent implementation, Spalding and others included a phase-diffusion term in the volume continuity equation [21]. By combining the Darken and Brenner concepts that the volume velocity is essential in defining the local material velocity at nonequilibrium, we recently derived the integral form of VCE, i.e.…”

Steady State Simulation of Gaseous Combustor Using Local Extiction Eddy Dissipation Concept

“…Study of turbulence effect on chemical reaction is challenging in many aspects. Comprehending of the complex effects of a macro level phenomenon (turbulence) on a molecular lever phenomenon (chemical reaction) is the main challenge [7][8][9]. Of particular interest is non-premixed combustion in a coaxial jet combustor configuration.…”
