Web2 feb. 2011 · Helical Ribbons and other proximity agitators The near impossibility of generating turbulence in viscous and non-Newtonian materials means that effective mixing depends on ensuring that all the fluid is moving. This can only be achieved with impellers that are large and which sweep out the whole vessel volume. WebIn 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 …

The operation of the geodynamo depends on the internal evolution of the planet because convection in the core is linked to the rate of cooling. The transport of heat through the mantle is crucial for powering the geodynamo, and even the existence of plate tectonics at the surface is an important factor.
