Simulation of rotation by gravity
Abstract
In order to gain information on the local heat transfer coefficients around the periphery of holes in the blades of gas turbines, the use of a gravitational system is proposed to simulate the effect of the forces caused by rotation. The corresponding Coriolis and Grashof number terms for the gravitational simulator of a rotating tube with coolant fluid are established. A gravitational model of an air cooled gas turbine blade appears to be feasible, but such a model for a water cooled system is infeasible due to the impracticable large size needed.
