RISNumerical Simulation and Parametric Study of a Supersonic Intake
was undertaken using the designed base case at a constant Mach number of 2 and at 0° angle of attack. The effects of various important parameters such as free stream Mach number, spike deflection angle, and back pressure ratio on the total pressure recovery, mass...
Performance Study of a Supersonic Inlet in the Presence of a Heat Source
location, size and shape. For the optimum condition, drag coefficient reduces considerably, inlet mass flow rate increases, but pressure recovery slightly decreases....
Performance Investigation of a Supersonic Air Intake in the Presence of the Boundary Layer Suction
.2 and at zero degrees angle of attack. Total pressure recovery, mass flow ratio, and flow distortion have been selected to assess the intake performance. The bleed slot is located upstream of the intake throat
perpendicular to the compression ramp surface...
A novel method for calculating natural gas density based on Joule Thomson coefficient
In natural gas measuring techniques, the natural gas mass flow rate is usually measured employing experimental facilities for density calculation, volume flow meters and other peripheral equipment such as temperature and pressure sensors. In order...
Novel natural gas molecular weight calculator equation as a functional of only temperature, pressure and sound speed
In city gate stations (CGS) experimental facilities are currently employed to specify natural gas compositions and subsequently calculate its density. Then, natural gas mass flow rate is calculated by employing an Ultrasonic Flow Meter (UFM), and a...
Mass transfer estimation during friction stir welding of aluminum alloy using smoothed particle hydrodynamics method
During Friction Stir Welding (FSW) process, mass transfer phenomenon was investigated using Smoothed Particle Hydrodynamics (SPH) method. Temperature distribution, strain rates and shear layer thickness were obtained ...
Mass flow rate prediction of temperature-driven gas flows through divergence micro/nanochannels
This paper presents an investigation of the mass flow rate of
rarefied gaseous flow in divergent micro/nano channels
compared with the results of straight channels. Direct
simulation Monte-Carlo (DSMC) method is used to solve...
Mass flow rate prediction of pressure–temperature-driven gas flows through micro/nanoscale channels
In this paper, we study mass flow rate of rarefied gas flow through micro/nanoscale channels
under simultaneous thermal and pressure gradients using the direct simulation Monte Carlo (DSMC) method.
We first compare our DSMC solutions...
A Thorough Study on Thermal Mass Flux of Rarefied Flow through Micro/Nanochannels
Most of the previous works on mass flux due to thermal creep focused on thermal creep due
to wall temperature gradient. In this work, we show that even without wall temperature
gradient there exists thermal ...
