Imagine a flying object, maybe a sphere or cylinder for simplicity, the gas flowing around the object has to flow around it, the gas is forced to move around the object. Such forces need to have a pressure gradient force ( volumetric force = ∇ pressure) , and the pressure change corresponds to a temperature change with an adiabatic relation.
Imagine the flying object at two different speeds, v and v + Δv, close to each other. Determine the difference in the temperature field in the surrounding gas between the two situations. My question is: If I artificially apply such a temperature field around an object would it accelerate? (Would the object go from speed v to v + Δv ? ) David
