The Kaplan turbine is smaller in size and construction is also easy. At low water heads, the Kaplan turbine works more efficiently and with high flow rates compared to other types of turbines. The overall efficiency of this turbine is good. Related article: Venturimeter Orifice Meter Francis Turbine. So that’s all for Kaplan Turbine.

Study the constructional detail of the Kaplan turbine and draw its fluid flow circuit. 2. Introduction: With a double regulation system, Kaplan turbines provide high efficiency over a broad range of configurations.

The efficiency  Apr 1, 2019 Furthermore, several fish survivability tests conducted on newly indexed and efficiency-optimized Kaplan turbines have found 48-hour hold time  This adjustment allows to adapt the turbine when the head and flow rate varies in order to increase part load efficiency. A doubled regulated Kaplan uses also  The static characteristics for flow rate and efficiency were identified. Models are presented in normalized values so that they can be reused to represent other  To enhance it's hydrodynamic efficiency by reducing weight, shape alterations, blade angle with combination of materials Aluminium alloy, Structural steel,  Jan 21, 2020 In this turbine waters enters the turbine radically and exits axially producing electricity more efficiently. This type of turbine is frequently used in  May 16, 2020 Variable geometry gate and turbine blades allow efficient operation for different flow conditions.

Since it is a reaction turbine, the reaction force of leaving the water is used to turn the runner of the Kaplan turbine. These turbines work at the high flow rate of water and low head with maximum efficiency that is not possible in Francis turbine. A unique feature of Kaplan turbines is that the blades changes as needed to maintain the highest efficiency under different water flow conditions. The water flowing through these turbines lose pressure. The Kaplan turbine is smaller in size and construction is also easy. At low water heads, the Kaplan turbine works more efficiently and with high flow rates compared to other types of turbines.

Relative efficiency measurements using the Winter-Kennedy method for relative flow Decreased efficiency is also visible in Figure 1, above, since for a given relative power output increase, efficiency will decrease, because it would then follow a partial helix curve. Knowing that a Kaplan turbine can produce up to 200 MW, we can evaluate the financial loss for an average 50 MW turbine with 92% efficiency at maximum output.
