Kaplan Turbine• The Kaplan turbine is a greatdevelopment of early 19thcentury.• Invented by Prof. Viktor Kaplanof Austria during 1913 – 1922.• The Kaplan is of the propellertype, similar to an airplanepropeller.• Kaplan turbine is a low headturbine and used for heads ofless than 80 meters.• HTFF 151-4 Turbine Headwater runner Tailwater Fig. Kaplan struggled with cavitations problems, and in 1922 abandoned his research for health reasons. In today’s lesson, we learned what are the parts of a Kaplan Turbine, how its work and advantages, disadvantages, and application of the Kaplan Turbine. hydroelectric power plant diagram. Related terms: Hydroelectric Energy known as CFD) and experimental measurements of a Kaplan turbine to find out how accurate the numerical methods really
Kaplan Turbines. The main parts of Kaplan Turbine are, 1. It was the first hydraulic turbine which work in low head and high flow rate.

Victor Kaplan obtained his first patent for an adjustable blade propeller turbine in 1912. CONSTRUCTION DETAILS OF KAPLAN TURBINE: 5: Details of the case study.
Fig. Scroll Casing. The velocity triangle at inlet and outlet of the Francis turbine is drawn in the same way as in case of inward flow creation turbine . Very Simple Kaplan Turbine Design Grant Ingram 30th January 2007 Nomenclature b blade height g gravitational acceleration H head k loss coeficient m˙ mass flow rate P power output Q volumetric flow rate r radial direction R radius U blade speed V absolute velocity, subscripts denote stations and components W relative velocity, subscripts denote stations and components x axial direction Kaplan Turbine is designed for low water head applications. KAPLAN TURBINE It is an axial flow reaction turbine. the only dimensions i need is for the blade runner Diameter to be 0.94m and the hub 0.31m with the shaft 3m long. as in case of Francis turbine, the discharge is radial at the outlet, the v elocity of whirl at the outlet ( i.e. Kaplan Turbines.
From: Fluid Mechanics and Thermodynamics of Turbomachinery (Sixth Edition), 2010. to know about this first of all let me tell you a pump is used to provide fluid energy which is derived from motor of pump(ie. From: Fluid Mechanics and Thermodynamics of Turbomachinery (Sixth Edition), 2010. Kaplan Turbine has propeller like blades but works just reverse. It consists of spiral casing, guide mechanism and draft tube of Kaplan turbine runner are similar to those of Francis turbine. This operates in an entirely closed conduit to tailrace. The ANDRITZ Hydro Kaplan turbine is utilized on a low head application with up to 90 m and a unit output of up to more than 230 MW. The degree of efficiency is very high with more than 95 %. INTRODUCTION: Kaplan-type hydraulic turbine in which the positions of the runner blades and the wicket gates are adjustable for load change with sustained efficiency, it is a purely axial flow turbine with a vertical shaft disposition. you can improvise for the rest as … Our Kaplan turbines also keep the environment in mind. DIAGRAM.
Power is recovered from both the hydrostatic head and from the kinetic energy of the flowing water. Kaplan turbine is employed, where a large quantity of water is available. Kaplan turbines could technically work across a wide range of heads and flow rates, but because of other turbine types being more effective on higher heads, and because Kaplan’s are relative expensive, they are the turbine of choice for lower head sites with high flow rates. In this article we will study about the Pelton wheel or Pelton turbine working, main parts, application with diagram.IT is a hydraulic turbine which is used in most of the hydroelectric power plant to generate electricity. With a double regulation system, Kaplan turbines provide high efficiency over a broad range of configurations. Draft Tube: The draft tube is an expanding tube which is used to discharge the water through the runner and next to the tailrace. I hope I am able to clear your all doubts, still, if you have any further query feel free to ask me in the comment section …
