Is there a version of aerodynamics that incorporates and intergrates the complete physics of...
Yes. The physics of sound wave propagation in air is explicitly included in trans-sonic and supersonic aerodynamics. The relative importance of sonic effects in aerodynamics is indicated by the so-cal …

Is there an easy explanation for this flow pattern?
Yes there is, as follows.
If we disturb a body of water by moving an object through it, we create waves which propagate away from the object as it moves. Those waves will have a certain height and in …

Why fast trains make a white noise sound?
Turbulent air motion is excited by a fast train and hence acoustic power is radiated by that turbulent air as a "WHOOSH" sound. Because air has mass, elasticity and compliance, extremely low and extre …

Is it possible to determine the position of the laminar-turbulent transition of a boundary-l...
Using computer simulations, it is possible to estimate the likely position of a laminar-to-turbulent transition. In fact, computer modeling of fluid flow has gotten so good in recent years that almost …

Transition from laminar to turbulent flow
the transition from laminar to turbulent begins to occur when the magnitude of the forces caused by viscosity (which tend to smooth out the flow and damp out instabilities) become smaller than the mag …

Free falling water from tap turns laminar to turbulent
fluid jets which are laminar and of small diameter get stretched out into thinner jets as they fall, because the head end of the jet is moving faster than the tail which is still attached to the water …

Why do mosquito coil smoke not rise in a linear manner even if there is no wind?
The smoke particles are tracers of air movement- in this case, the air which rises because it was warmed up slightly by the burning coil. The air rises very slowly which means there's not much energy …

Pressure recovery - what is it and why do we want it?
The example you furnish is not a useful application of pressure recovery, it just illustrates how it happens. The principle of pressure recovery is important in the design of for example radial flow j …

Has car round back any aero advantages?
The idea of a round and tapered rear end on a car is to delay flow separation at the backside of the car, which adds to drag. Tapering and lengthening the car adds to its wetted area, which also adds …

Test tank physics
You are right- there are a number of scaling parameters called nondimensional groups or similitude parameters which tell you by how much the viscosity, density, and surface tension of the liquid must …

What is the structure on SUV's top back edge?
at the speeds at which an SUV travels, the aerodynamic effect of these "spoilers" is minimal. They serve to deflect airflow above the rear hatch in such a way as to minimize dirt and mud buildup on th …

How do flat insect wings generate lift?
Note that uncambered wings on insects are flexible, and twist while being beaten up and down in air into complex 3-dimensional curves. The lift is generated by a cyclic mechanism called vortex sheddin …

Can protrusions on the smooth surface of a floating (or flying) body not slow it down, but a...
The protrusions cannot yield an acceleration of the body in the direction of the body's motion through the fluid. If so, then bullets fired into the air would speed up instead of slow down as they fly …
