Experimental Investigation of The Performance and Peak Power Output of A Fluidyne Engine

Abstract

The purpose of this study was to study the operation of Fluidyne engine, including experiments to find the maximum power of the engine and the appropriate water level of the engine, using water as a liquid piston in the displacer cylinder and using an electric heater as a heat source for the engine.

          The initial experiment is an experiment to find the power of the engine at the water level which is the center of the electric heater. The experiment will find the power of the engine at different heat input, starting from 100 Watts to 700 Watts. The next experiment will change the water level in the tuning column by increasing and decreasing the water level from the middle of the heater by 3 centimeters at a time. In changing the water level, a total of 9 levels were changed. It was found that the water level at 29.5 centimeters was the appropriate water level. The maximum power obtained from the engine is 0.1894 W at a heat quantity from the heat input 568 W, the water level fluctuation of the water stream in the tuning column is 510 mm, the frequency of the water stream in the tuning column is 1.133 Hz, the engine efficiency is 0.033%.
