To contain the water pressure, the reaction turbine needs to be entirely enclosed, and it also needs to be totally submerged in the water flow. In contrast to impulse turbines, reaction turbines are typically employed in applications with lower head and larger flows. Reaction turbines come in four different varieties: mixed flow, axial flow, oblique flow, and flow through flow Water Turbine Market. The draught tube, an expansion section, is located at the outflow of the reaction turbines. The draught tube's job is to capture the flow's kinetic energy at the runner's exit and transform it into pressure so that it can be recovered. The efficiency of the turbine is significantly impacted by the kinetic energy recovery of the draught tube.
