Alterations in Critical Radii of Bluntness of Shock Wave Boundary Layer Interaction
Publisher: American Society of Civil Engineers
Abstract: Any configuration consisting of flat plate attached to a ramp experiences shock wave boundary layer interaction (SWBLI) at supersonic or hypersonic Mach numbers. This interaction can lead to flow separation at the ramp ...
Accelerometer-Based Force Balance for High Enthalpy Facilities
Publisher: American Society of Civil Engineers
Abstract: A single component accelerometer-based force balance is developed, calibrated, and used for high enthalpy applications. Functionality of this force balance, for such applications, is demonstrated for the first time during ...
Delusive Influence of Nondimensional Numbers in Canonical Hypersonic Nonequilibrium Flows
Publisher: American Society of Civil Engineers
Abstract: A finite volume–based unstructured inviscid flow solver has been developed for the study of nonequilibrium effects in high enthalpy flows. Four different inviscid flux computation schemes are tested for literature reported ...
Experimental Exploration of Bioinspired Planar Wingtip Devices for a Flat-Plate Wing in the Low Reynolds Number Regime
Publisher: American Society of Civil Engineers
Abstract: This study investigates the use of planar wingtip attachments to improve the lift generating performance of low aspect ratio (AR) flat-plate wings in the low Reynolds number (Re) range (<105). Inspired by nature’s ...
Laser Based Calibration Technique of Thin Film Gauges for Short Duration Transient Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surface temperature history and determination of convective heating rate are the important activity in many research programs for devising an effective cooling system in internal combustion engines ...
Aerothermodynamic Assessment of Spiked Configuration for Drag Reduction at Hypersonic Speeds
Publisher: ASCE
Abstract: Aerothermodynamic analysis was performed for blunt-body configurations with spikes mounted to determine drag reduction effectiveness. In-house perfect gas and chemical nonequilibrium solvers were utilized. The analysis ...
