Turbine has a major role in turbomachinery; extract energy from working fluid, therefore to produce useful work. In the study of turbine, the axial turbine and inward flow radial turbine
are tending to have more focus in the literature. The present work is a thesis project presenting a review of the outward flow radial turbine. The purpose of the thesis is to
discover the advantage/disadvantage of the outward flow radial turbine. Also, it discusses the new development of outward flow radial turbine in the modern days.
It discovered that the outward flow radial turbine has a main disadvantage, which is the fluid flow from a smaller radius to a larger radius, it give the reduction of work. But this outward
flow concept, it brings an advantage to the outward flow radial turbine, that the naturally increase with passage area. It gives efficient in the expansion process.
In the modern day, Euler Turbine is available in the market, and this turbine is a type of outward flow radial turbine. Based on the design data of a realized model of the Euler Turbine, it found that the Euler Turbine is able to create a large amount of specific work done from the absolute and relative velocity component, thereby to overcome the amount of reduction of work. It found that the Euler Turbine is able to achieve to an isentropic efficiency of 84.298% in general. It is also possible to achieve to an isentropic efficiency of 89.696% with a well-design.
