Manipulation of Flow Characteristics Using Laser Energy Deposition

The idea of travelling safely from London to New York under three hours or even ‘access to space’ may sound appealing to many people, whether they are travelling for business or tourism. The high-speed civil transports will be able to achieve such flights; however, travelling at high speeds entails overcoming adverse effects, such as regions of high heat transfer and surface pressures, unsteady shock waves, together with the requirement of drag reduction. One method of flow and flight control is laser-based energy addition. The project aims to reduce drag and weight of high-speed vehicles. As a result of the reduced fuel consumption, the vehicles can be more environmental friendly. The overall objectives are: 1) Make significant advances and novel contributions in the state of the art by providing new physical insight of the induced interactions, to rectify their adverse effects by employing laser-based deposition systems; 2) Gain the experience, knowledge, and credibility to establish the Fellow as a world class engineer and researcher. The proposed study utilised laser-based deposition systems for the development of: a) Mitigation schemes for the avoidance or modification of localised regions of high heat transfer and surface pressure of high-speed vehicles; b) Methods for controlling local flow field characteristics and the location of shocks e.g., in engine inlets, and wing/body surface. This fellowship has provided Dr Ukai with support and training in all scientific and engineering aspects concerning the development, realization, characterization, modelling and simulation of laser-based energy deposition systems for flow and flight control.
