Radial Inflow Turbine Manufacturers

Radial Inflow Turbines are used in turbochargers with capacities up to about 1000 HP. It has a nozzle to direct the flow of gases to turbine wheel at the best possible angle. The incoming fluid usually passes through a set of nozzles that cause the fluid to swirl and thereby entering the turbine rotor at the proper relative velocity. The flow then continues through the rotor where it continues to expand and impart energy to the rotor. The fluid then leaves the rotor near the rotational centerline. The blade angles at the rotor exit are designed to remove exit swirl as the fluid leaves the machine. This minimizes the energy in the exhaust flow thereby increasing the turbine efficiency. In some designs the inlet nozzles are replaced with an inlet scroll sized to provide the swirl to the rotor. The most common application for the radial inflow turbine is the exhaust driven turbocharger used on internal combustion engines.
