<p>Gas is contained in four tubes connected to form a closed rectangular circuit in a vertical plane. There is a heat exchanger (W3) at the top of one vertical leg and another (W1) at the bottom of the other leg. When the heat exchangers are out of use the gas in the two vertical legs (K1,K2) is at the same conditions with increasing potential downwards. A single impulse sets the gas in motion round the circuit. As it flows it undergoes an adiabatic expansion (K2) followed by an adiabatic compression (K1). A turbine (T) in the top horizontal branch can extract useful work from the gas.</p> |
