Summary on Grant Application Form |
|
The fluid flows to be studied here are produced mainly by a rotating configuration of thin blades (as in helicopters, airborne seeds, food mixers, hover mowers). Fully nonlinear theory and computations are proposed on the 3D unsteady rotary boundary-layer system which generally describes the blade-wake interactions present. Theory is to cover extremes of large gaps, small gaps, many blades, and the far-outboard response, while a robust flexible computational method is to deal with the variety of rotary blade arrangements. Numerous new kinds of interaction are involved, specifically multiple blade-wake ones, global inner-outer ones at tiny incidence angles, viscous-inviscid ones near corners, edges and tips, and doubly viscous ones for dense blade-gap arrangements. The research centres on 4 specific items (i) - (iv) and follow-ons. There are to be close contacts with the major industrial beneficiaries, Westland, MOD, Kenwood.
