Philip Geoffrey Saffman
Applied Mathematics and Aeronautics at the California Institute of Technology.[7][8][9][10][11][12][13][14]
Education and early life
Saffman was born to a
Cambridge Mathematical Tripos in 1954 and was awarded his PhD in 1956 for research supervised by George Batchelor.[4]
Career and research
Saffman started his academic career as a lecturer at the University of Cambridge, then joined
viscous fingering of fluid boundaries,[16] a phenomenon important for its applications in enhanced oil recovery, and for the Saffman–Delbrück model of protein diffusion in membranes which he published with his Caltech colleague and Pasadena neighbour Max Delbrück. He made important contributions to the theory of vorticity arising from the motion of ships and aircraft through water and air; his work on wake turbulence led the airlines to increase the minimum time between takeoffs of aircraft on the same runway.[7][17][18] Saffman also studied the flow of spheroidal particles in a fluid, such as bubbles in a carbonated beverage or corpuscles in blood; his work overturned previous assumptions that inertia was an important factor in these particles' motion and showed instead that Non-Newtonian properties of fluids play a significant role.[12][19]
Along with his many research papers,[14] Saffman wrote a book, Vortex Dynamics,[5][6] surveying a field to which he had been a principal contributor. Russel E. Caflisch writes that "This book should be read by everyone interested in vortex dynamics or fluid dynamics in general."[20][21]
Awards and honours
Saffman was elected a
water waves.[2]
Personal life
Saffman was survived by his wife (Ruth Arion whom he married in 1954), three children (Mark, Louise, Emma), and eight grandchildren (Timothy, Gregory, Rae, Jenny, Nadine, Aaron, Miriam, Alexandra and Andrey.[1][8]
