Performance Analysis of Thermoelectric Based Automotive Waste Heat Recovery System with Nanofluid Coolant

Output performance of a thermoelectric-based automotive waste heat recovery system with a nanofluid coolant is analyzed in this study. Comparison between Cu-Ethylene glycol (Cu-EG) nanofluid coolant and ethylene glycol with water (EG-W) coolant under equal mass flow rate indicates that Cu-EG nanofluid as a coolant can effectively improve power output and thermoelectric conversion efficiency for...

Performance Driven Validation Applied to Video Processing

This paper presents a systematic method to validate implementations of video processing algorithms. This is useful when translating algorithms implementations from a floating-point to fixed-point precision. The method takes advantage of an automatic word length determination tool and an Objective Image Quality Metric (OIQM) to implement a performance driven validation. Since results obtained wi...

A steam Rankine cycle with two-stage pumping to enhance the waste heat recovery from internal combustion engines

In this research, a high-temperature Rankin cycle (HTRC) with two-stage pumping is presented and investigated. In this cycle, two different pressures and mass flow rates in the HTRC result in two advantages. First, the possibility of direct recovery from the engine block by working fluid of water, which is a low quality waste heat source, is created in a HTRC. Secondly, by doing this, the mean ...

A feasibility study and economic analysis for application of nanofluids in waste heat recovery

This paper presents a comprehensive theoretical, experimental, and economic study on the application of nanofluids as heat transfer fluid in waste heat recovery systems. The research work was conducted in a steel-making complex in which a plate heat exchanger had been used to recover heat from hot process water. The system was theoretically modelled and the effects of using nanofluids as he...
