"Radial means that the fluid is flowing in radial direction that is either from inward to outward or from outward to inward. If the fluid is flowing from inward to outward then it is called outflow radial turbine. 1. In such turbines, the water enters at the centre of the wheel and then flows outwards (i.e., towards the outer periphery of the wheel). " - Inward flow radial turbine
