Forced convective heat transfer plays a significant role in almost all industrial sectors. Examples include cooling of microelectronics, process intensification in the chemical industry, heat exchange/waste heat recovery in power plants and cooling of car engines, to name but a few. In special, a study of forced convective laminar boundary layer behaviour on a flat plate has attracted the atten...

WASTE OIL RECOVERY. Prior to 1960, a significant portion of the demand for automotive lubricating oil was met by re-relined used oil. At the time, 150 re-refineries produced 300 million gal of motor oil annually. Since 1960, however, the production of re-refined oil has steadily declined. In 1981, for example, out of about 1.2 billion gal of automobile lubricating oil and 1.6 billion gal of ind...

Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extr...

Submitted: Jun 14, 2013; Accepted: Jul 27, 2013; Published: Aug 07, 2013 Abstract: The paper deals with the study of a control strategy for a generalized thermodynamic ORC power plant utilizing waste heat by using dynamic modelling technique. As Organic Rankine Cycle (ORC) is particularly suitable for the recovery of energy from low-quality heat sources. Therefore a generalized proposed predict...

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 heat t...
