Chimney effect theory
WebJun 28, 2014 · The solar chimney is one of the technologies which work on the principle of buoyancy, where air is heated through the greenhouse effect generated by solar radiation (heat energy) at low costs. The solar chimney is a passive solar ventilation system (non-mechanical) that can be installed on roofs or in walls. In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from either side of the body forming a Kármán vortex street. The fluid flow past the object creates alternating low-pressure vortices on the downstream side of the object. The objec…
