Thermosolutal convection in a square cavity filled with air and submitted to an inclined magnetic field is investigated numerically. The cavity is heated and cooled along the active walls with a mass gradient whereas the two other walls of the cavity are adiabatic and insulated. Entropy generation due to heat and mass transfer, fluid friction and magnetic effect has been determined in transient...

Two-dimensional numerical study of flow and temperature fields for laminar natural convection and radiation in the inclined cavity is performed in the present work. The walls of the square cavity are assumed kept at constant temperatures. An absorbing, emitting, and scattering gray medium is enclosed by the opaque and diffusely emitting walls. The set of governing equations, including conservat...

Airframe noise is equal to or louder than engine noise during the landing approach of a commercial aircraft. Cavity noise is one of the most important airframe noises. When airflow passes over an open cavity, due to vortex shedding at the upstream edge of the cavity and the geometry of the cavity, high-level aero-acoustic noise may be generated. When the incident acoustic waves produced by the ...

This paper presents experimental data examining the flameholding performance of a scramjet cavity with an inclined front wall. Mach 8 flight-equivalent flows were delivered to axisymmetric, combustor via T4 reflected shock tunnel. The model was designed permit interchangeable geometries. Each examined maintained length-to-depth ratio 4, depth mm and close-out angle 22.5 deg. first possessed 90 ...

The following case of severe intra-peritoneal haemorrhage from a corpus luteum is of considerable interest at this time, as gyntecologists are now again recognising that bleeding into the pelvis may be due to other causes than rupture of an ectopic pregnancy. I am inclined, from my experience in abdominal surgery, to think that a certain degree of haemorrhage into the peritoneal cavity, ovarian...

Natural convection in an inclined porous cavity with positively or negatively inclined angles is studied numerically for time-periodic boundary conditions on the left side wall and partially active thermal boundary conditions on the right wall. The results show that a partially active thermal boundary condition on wall B can lead to heat transfer between two opposing vertical side walls. Temper...

In this work, mixed convection from an inclined square cylinder in a cavity is numerically investigated. A commercial CFD solver Ansys Fluent used to solve the problem. First, located at center of cavity, then location changed along x-axis. The walls are assumed be adiabatic and isothermal boundary condition. Reynolds number, Re varies 100 300 Grashof numbers, Gr range 103 105 throughout work. ...
