Research

Soward is known for his work on magnetohydrodynamics (MHD) and especially dynamo theory, and also for his contributions to linear and nonlinear stability theory. He used asymptotic analysis to solve a number of outstanding problems in applied mathematics. By a new pseudo-Lagrangian technique for studying lightly damped fluid systems, he elucidated previously inexplicable features of Braginskii's geodynamo. Soward has provided explicit examples of steady fast dynamo action, thus disproving a conjecture that such dynamos did not exist.^[4]

He identified new rotating modes of nonlinear convection in rotating systems, and in collaboration with Steven Childress, established an MHD dynamo model in a rapidly rotating Bénard layer; he also gave the first demonstration that situations exist where oscillatory MHD dynamos generate magnetic fields more readily than steady flows can. He collaborated with Eric Priest to provide the first mathematically consistent account of the Petschek mechanism of magnetic field line reconnection. Soward also gave the first complete solution of the Stefan (freezing) problem in cylindrical geometry; with C.A. Jones, he provided the first completely correct solution of the spherical Taylor problem.^[4][5]

Awards and honours

Soward was elected a Fellow of the Royal Society (FRS) in 1991.^[4][5]
