Abstract

When undertaking the design of a new ship concept many aspects need to be explored and studied. In this work two central aspects are explored:
i) The understanding of the thermal response of ship propulsion systems to load variations.
ii) The recovery of waste heat from hot exhaust (usually from a prime mover).
Both of these concepts are important to the primary design and operation of the ship. Thermal response is integral because this will allow concealment of vital ship systems while maintaining proper cooling, and waste heat recovery can contribute to the overall efficiency
The thermal study reported here, was conducted at the Center for Advance Power Systems. The thermal loads on this system were studied for various motor load conditions. Theoretical models of this system were also developed. From these models advanced simulations and studies can be performed to gain addition understanding of the system.
The final part of this work experimentally investigates waste heat recovery from a hot stream using an absorption refrigerator. The effects of varying hot stream inlet temperature and flow rate are reported. From these results we can identify the feasibility of absorption refrigeration run by the waste heat of a ship propulsion system.
