A note on the centrifugal scaling of horizontal,isothermal, liquid-gas flows without mass transfer

The use of rotation to simulate increased gravity in scale models of horizontal liquid-gas flows is examined. The influences of Coriolis forces and natural gravity in the model are seen to be small provided that high rotation rates are used, and large length scale-down factors can then be achieved. The modelling of compressibility and gas-viscosity effects, however, is not normally possible and these must therefore be small in the original flow.
