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. Because all the velocity head is converted into the pessure head at stagnation point. WebFeb 1, 2024 · When two "charges" are equal and opposite, there'll be no neutral point at which the electric fields from the charges balance each other.Similarly, for source and sink with equal strengths, there's no stagnation point. See more on bipolar coordinates. If you see another case here, there'll be a neutral point such that more than one field lines meet … WebThe exclusive behaviour of hybrid nanofluid has been actively emphasized due to the determination of improved thermal efficiency. Therefore, the aim of this study is to highlight the stagnation point Al2O3-Cu/H2O hybrid nanofluid flow with the influence of Arrhenius kinetics and thermal radiation over a stretching/shrinking sheet. cfsei tech notes
