Abstract
Abstract: A small cooling blower is simulated numerically using FINFLO flowsolver with quasi-steady assumptions. The blower has 13 blades with an outer radius of 6 mm. The angular speed is 1047.2 Rad/s and the Reynolds number 2450. The size of the blower is 15 x 15 mm³. The Low-Reynolds number approach is utilized with a k-ω turbulence closure. The case is also simulated assuming completely laminar flow. Main result: Pressure rise, efficiency and torque are obtained from the simulated slowfield. Far curve is generated from the simulations of four air flow rates.Description
