Abstract: A process is proposed for integrating the laserassisted machining (LAM) and laser surface heat treatment (LSHT) in a single operation. Experimental and numerical investigations were carried out. LSHT tests were performed ...

Abstract: An equal polygon opposing jet can withstand huge wave drag and serious aerodynamic heating in hypersonic flow conditions. The opposing jet is able to change the flow field structure, and then it improves the aerodynamic ...

Abstract: For the purpose of understanding the influence of stabilizing agents on the internal structure of aggregates in treated soils, seven soil samples were prepared for tests according to type and quantity of stabilization ...

Abstract: The mixing efficiency of the fuel and the supersonic freestream has a great impact on the operation of the scramjet engine because of the very short residence time. In the current study, the cantilevered ramp injector was ...

Abstract: A hybrid modeling approach based on computational fluid dynamics (CFD) and finite element method (FEM) is presented to simulate and study cryogenic machining (CM) of Ti–6Al–4V alloy. CFD analysis was carried out to study ...

Abstract: As one of the most promising propulsive systems for future hypersonic vehicles, the hydrogen-fueled dual-mode scramjet combustor has drawn the attention of an ever increasing number of researchers. The two-dimensional ...
