Investigation of groundwater quantitative change, Tehran Province, Iran
Groundwater Aquifer Level changes Decline Homand-Absard Iran
2018/3/23
Changes in groundwater level in Homand-Absard plain, located in north-west of Kavir-e-Markazi watershed and east of Tehran province, were studied. The used research method was descriptive approach, an...
Investigation on a new method of adaptive drag reduction and nonablation thermal protection system for hypersonic vehicles
hypersonic drag reduction heat flux jet aerospike numerical simulation
2013/9/2
A new adaptive drag reduction and nonablation thermal protection method named Telescopic Selfaligning JetSpike (TSAJS) is proposed to improve the conventional spiked method employed in hypersonic v...
Investigation of Non-Newtonian Micropolar Fluid Flow with Uniform Suction/Blowing and Heat Generation
Stagnation point flow Stretching sheet Heat generation Finite difference method
2009/10/9
The steady laminar flow with heat generation of an incompressible non-Newtonian micropolar fluid impinging on a porous flat plate is investigated. A uniform suction or blowing is applied normal to the...
Numerical investigation of rotor-stator interactions in a 1.5-stage low-speed axial compressor
axial compressor rotor-stator-interaction periodic unsteady blade pressure uctuation unsteady blade pressure force
2010/3/11
The relative motion of rotor and stator leads to viscous and inviscid interactions between the blade rows. This is the reason why the °ow in turbomachines is periodically unsteady. The unsteady °ow &m...
