Laminar boundary layer velocity profile The aerodynamic boundary layer was first defined by Ludwig Prandtl in a paper presented on August 12, at the third International Congress of Mathematicians in Heidelberg, Germany. It simplifies the equations of fluid flow by dividing the flow field into two areas: one inside the boundary layer, dominated by viscosity and creating the majority of drag experienced by the boundary body; and one outside the boundary layer, where viscosity can be neglected without significant effects on the solution. This allows a closed-form solution for the flow in both areas, a significant simplification of the full Navier—Stokes equations. The majority of the heat transfer to and from a body also takes place within the boundary layer, again allowing the equations to be simplified in the flow field outside the boundary layer. The pressure distribution throughout the boundary layer in the direction normal to the surface such as an airfoil remains constant throughout the boundary layer, and is the same as on the surface itself.

Skickas inom vardagar. Recensioner i media From the reviews: "We find here a book where the theory is developed with rigours in parallel with a strong physical intuition. Comparison with experiments and simulations are always proposed and carefully analysed.
The book contains at the end a very rich and complete bibliography I warmly encourage everyone interested in boundary-layer theory to have this book in his bookcase. I do recommend the book highly, especially for its long historical perspective, including all the diagrams comparing theory and experiment that remind us that engineering is practical He studied the mathematics, physics and applied mechanics at the University of Jena, Vienne and Goettingen and was promoted After a short period at Dornier in Friedrichshafen where he was responsible for the new wind tunnel he joined the Technische Universitat Braunschweig in and became professor in at the age of Herman Schlichting became an Emeritus Professor in Klaus Gersten is a German mathematician, engineer and expert in fluid mechanics.
