Abstract: Experimental measurements of the steady forces on a central cluster of tubes in a rotated triangular array (P/D=1.5) subjected to two-phase air–water cross-flow have been conducted. The tests were done for a series of void ...

Abstract: An approximate analytical model, to predict the drag coefficient on a cylinder and the twophase Euler number for upward twophase crossflow through horizontal bundles, has been developed. To verify the model, two sets of ...

Abstract: This work investigates the effect of tip clearance size and operating temperature on the predictions of the critical rotor speed at which nonsynchronous vibrations (NSV) can be encountered in a turbine engine axial flow ...
