Immission, Deposition, Sedimentation,temperature field can also be divided into two regions: in the region close to the wall, where the thermal conductivity λ plays a role, and a region where λ can be neglected. If both a velocity field and a temperature field exist, there is generally also a mutual coupling between these two fields.

Fundamentals of Boundary-Layer Theoryy at the wall. At large Reynolds numbers this transition takes place in a thin layer close to the wall, called by L. Prandtl (1904) the . or .. As will be shown, the boundary layer is thinner the higher the Reynolds number, i.e. the smaller the viscosity.

Thermal Boundary Layers with Coupling of the Velocity Field to the Temperature Fieldperature field. In addition, the temperature dependence of the density means that buoyancy forces in the gravity field appear in the momentum equation. These buoyancy forces alone can produce flows called . (or .). If buoyancy forces due to gravity also occur alongside the forced convection discussed in the last chapter, we speak of ..

Interim Period: Carnap Versus Popper, liquid jets. On the other hand, the theory of ideal fluids is useless when faced with the problem of calculating the drag of a body. It predicts that a body moving subsonically and uniformly through an infinitely extended fluid will experience no drag (D’Alembert’s paradox).

Aus dem Reiche der Vorstellungen,osition of the separation point was quite dependent on how much the velocity of the outer flow was decelerated. Furthermore, in the last chapter we showed that, for temperature dependent physical properties. cooling and heating affected the position of the separation point.
