The flow due to the presence of a solid surface at in planar stagnation-point flow was described first by Karl Hiemenz in 1911, whose numerical computations for the solutions were improved later by Leslie Howarth. A familiar example where Hiemenz flow is applicable is the forward stagnation line that occurs in the flow over a circular cylinder. The solid surface lies on the . According to potential flow theory, the fluid motion described in ter… WebThe exclusive behaviour of hybrid nanofluid has been actively emphasized due to the determination of improved thermal efficiency.

Webthe stagnation point. As an alternative we use the following (crude) approximation. The contribution of the segment between well and stagnation point is approximated empiri-cally. It is based on the longitudinal second moment for radial mean flow conditions [after Indelman and Dagan, 1999], for which we can use their analytical approximation ... WebA stagnation point is a point in a flow field where the local velocity of the fluid is zero. The Bernoulli equation shows that the static pressure is highest when the velocity is zero and hence static pressure is at its maximum value at stagnation points.
