FactChecker replied to the thread Undergrad What is the most impactful way of introducing Laplace transforms?.Aero engineers in flight control design or stability and control use it heavily. -

@A.T. T Great article, where did you find it. I think a speedup is implied already for flow over an obstacle, such as a building... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Would that be true in the steady state flow or only in turbulence? Some diagrams here seem to indicate reduced velocity everywhere yet... -

If you google "optimal placement wind turbine hill" or similar, you will find more information on exploiting obstacles to improve wind... -

I might also mention, but not teach, the z-transform. It's essentially the Laplace equivalent for discrete time systems; digital... -

It is THE main tool for linear systems analysis (often non-linear systems too). Analog circuit design, filter design, control systems... -

The streamline figures in post 27 can be somewhat deceiving at first glance. The streamline figure spacing is shown compressed, rather... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.There are other things going on. Please try to understand Bernoulli's equation, which gives the trade-off between pressure and velocity. -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Yes. So that is where the velocity can come from -- decreased pressure. This just means that the random directional movement of atoms... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Sorry. I stand corrected. I was thinking about incompressible fluid flow. Thanks. -

I don't think that's the right interpretation. The flow-speed plots in fig. 6 of my post #26 show lower speeds (blue) everywhere around... -
FactChecker replied to the thread Undergrad Light clock treating horizontal and vertical motion differently?.I disagree. IMO, most of the explanations compare a "stationary" light clock to a "moving" light clock. The experimental result that the... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Good point. I think that is the unexpressed question of the OP. The diagrams that @renormalize included in post #27 seems to indicate... -

Please look at the standard form of Bernoulli's equation @FactChecker provided and tell us what you see the answer is. You've been... -

The Bernouilli equation that one mostly sees, and the one that is presented as an introduction to fluid flow, is of the form in post 42...
