Abstract
In the present study, a water-piston engine driven by the low temperature waste heat is developed and numerical simulations and experiments are conducted to establish the steady operating condition. Both numerical and experimental results show that present experimental apparatus is not capable to attain the steady oscillation state. However, these results show the importance of the appropriate balance between the amount of supplied steam and condensed water in water-piston engine. Additioionally, numerical results and experimental results demonstrate the availability of intermittent steam supply equipment and upper vertical tube cooling devices, respectively. Hence, the experimental apparatus will be improved based on present results in the future.
