Witold Szablewski graduated as a physicist from Berlin University in 1932. Up to the end of World War II, he was involved in aerodynamic research, first with Focke-Wulf in Bremen, then at Göttingen University. He was from 1948 a scientist of the Department of Applied Mathematics of the Berlin University. As a founding member of the section of applied mathematics and mechanics of the German Academy of Sciences in Berlin in 1955 he headed the section turbulence and boundary layers of its Institute from 1960. Szablewski was appointed in 1961 professor of fluid mechanics at the Berlin Academy of Sciences. He was a Member of the Berlin Mathematical Society, of the Gesellschaft für Angewandte Mathematik und Mechanik GAMM, and the Scientific Association for Aviation, Cologne.

\

Szablewski devoted his entire career to turbulent flow and the boundary layer theory. Starting with the first papers in 1951, he contributed during more than 30 years to relevant questions of turbulent flow. He thereby started from the Prandtl boundary layer equations and admitted simplifications that allowed for a closed form solution of the problem. These involved converging and diverging channels, mixing of two air streams of almost equal speed but different temperature, velocity profiles for turbulent flows in zones of pressure variations, vortex flow within a cylinder, turbulent mixing, parallel streams of turbulent flows, the energy spectrum of homogeneous isentropic turbulence, or the similitude laws of turbulent flows. In the 1970s Szablewski published two books summarizing partly his earlier findings in turbulent flows.
