چکیده
In this study, simulation results for fluid flow around a cylinder are are simulated using experimental modeling parameters with suitable rheological behavior the flow around rotating cylinders in turbulent flow with fluid is simulated, firstly the two-dimensional incompressibility problem is considered , thermal boundary conditions of constant temperature on the pipes are considered. It has also been tried to change the behavior of flow lines and velocity profiles and temperature curves, as well as by changing the fluid behavior index, its effect on velocity profile, lift coefficient versus time has been investigated.result shows that the cylinder to force the surrounding flow to rotate along with the cylinder. This will create a vortex that hastens the speed of the air on top of the cylinder and at the same time retarding the speed of air below the cylinder. We can see that as the cylinder rotates, the lift improves, but not at higher flow speed . The faster the cylinder rotates, the higher the lift force gets. Also, the lift force improves exponentially as the airspeed increases The results show that at low speeds, the lift multiplier is zero and begins to increase and decrease sinusoidally from ۰.۵ to ۳ seconds higher speed rotation of the cylinder greatly changes the speed of the surrounding flow, thus better lift.کلیدواژه ها
