PARTICLE LADEN AIR FLOW VISUALIZATION IN A MULTI-ROTOR CONFIGURATION OF A LAWN MOWER HOUSING
Краткое описание
This experimental work presents the flow patterns observed in a multi-rotor system that is enclosed in a housing. Flow observations are performed in a three-blade lawn mower housing, and large particles are used in the flow to simulate grass clippings. Most rotating machinery uses multiple rotors in the same shaft. In a lawn mower, the grass-cutting blades are mounted side by side, and the flow created by one blade significantly influences the flow created by its neighbors. Two-blade types are used in combination with several rotation speeds and different rotation directions to obtain a set of flow observations useful for the equipment designers. The flow is observed to be actively influenced by the particles because the blades propel them on impact. It is observed that loading on the three rotating blades is unequal and particle distribution changes in accordance with the direction of rotation.
