Heatline Visualization of Natural Convection in Cavity Subjected by Different Heat Flux Profiles and Filled with Two Immiscible Fluids of Sulfuric Acid and Air
The natural convection heat transfer is investigated in the cavities filled with two immiscible fluids of sulfuric acidwater (25-75%) and air with different profiles of heat flux from side walls. The heatline visualization approach is employed to detect the heat energy path in the cavity from heat sources to heat sinks. The operating fluid is sulfuric acid-water (25-75%) at the bottom region and air at the top of the cavity. The Navier-Stokes equations are solved based on two-dimensional form, and finite volume approach is utilized. The side walls are heated variable heat flux and no-slip condition is applied to them. The top and bottom walls are cooled by environment temperature with no-slip condition. The influences of different governing parameters of Rayleigh number (〖10〗^3<Ra<〖10〗^5), and four different variable distributions of heat flux on the flow structure, temperature field, velocity and temperature distributions, average Nusselt number, skin friction coefficient and heatlines have been presented comprehensively.
Numerical Study on Dynamic Stall of Low Reynolds Number Flow Around Boom Mounted U-Tail of FARIDUAV
This study focuses on tail aerodynamic modeling with CFD simulation of an experimental unmanned aerial vehicle (UAV) in horizontal and vertical section separately. This aircraft with special capabilities has moderate maneuver performance, and predicting the aerodynamic behavior requires knowing that when dynamic stall will occur even in tail. The unsteady nature of the flow field around UAV tail, and the configuration of the generated lift and drag forces must be understood in order to optimize the comfort control system. As a result, flow around the tail and trailing-edge separation of elevator and rudder in horizontal and vertical tail at low Reynolds number with special angle of attack has been simulated .Finally, a custom three- component force balance for measuring lift , drag and moment is described in detail. The results indicate that maximum allowable angles of deflection are about 13 and 17 degree in horizontal and vertical tail, respectively. Moreover, each 1 degree of deflection decreases almost 0.35 degree horizontal tail stall angle.
