Discuss efficiency of joules cycle vs carnot cycle?
1 Answer | add yours
The thermal efficiency of the joules cycle is calculated using the ratio of the exit temperature of the compressor to the atmospheric temperature. The thermal efficiency of the Carnot cycle is calculated using the ratio of the highest temperature in the cycle to the atmospheric temperature. The exit temperature of a compressor is never the highest temperature in the cycle, which occurs in the internal of the engine. Therefore, the temperature ratio for the joules cycle will always be lower than the temperature ratio for the Carnot cycle for any given maximum cycle temperature, and consequently, the joules cycle is less efficient than the Carnot cycle.
