Heat transfer coefficients of particulate in tubular heat exchangers
This experimental study explores the heat transfer from heated bare and finned tubular surfaces to particulates in packed bed cross flow. The results from this experiment will be used to help select the type of particulates that will be used. Additionally, these results will assist in estimating …

Comparison of heat flux standards for calibrating heat flux gages at elevated temperatures and high heat flux levels
… a set of standards for use in calibrating heat flux gages at elevated temperatures in a radiant heat transfer environment by comparing several "trial" standards. Ideally, the same incident heat flux is derived from each standard when exposed to the same heat source. Three heat flux …

Heat and fluid flow analysis in a molten CuCl heat exchanger
… can be coupled to nuclear reactors to supply its heat requirements. The cycle generates hydrogen by splitting water molecules through a series of chemical reactions. Thermal management within the cycle is crucial for improving its thermal efficiency. The cycle has an average theoretical efficiency …

Heat Transfer and Thermal Process Design in Scraped-Surface Heat Exchangers
Performance and heat transfer characteristics of a scraped-surface heat exchanger (SSHE) for use in ultra-high temperature processing of low-acid liquid foods was evaluated using a Contherm 6 x 2 pilot-scale unit. Independent variables tested were steam pressure, blades rotational speed, inlet

Feasibility study of heat pumps for waste heat recovery in industry
… to assess the feasibility of implementing the heat pump for waste heat recovery. Through analysis, the focus was narrowed down from a site wide audit, to a departmental breakdown and then eventually to a specific process; the wort boiler. Three different alternatives were investigated and the …

Investigation of a novel solar photovoltaic/loop-heat-pipe heat pump system
… technologies by incorporating an innovative loop heat pipe (LHP) and a typical heat pump. In addition, a coated aluminium-alloy (Al-alloy) sheet replaces the conventional baseboard for the PV cells to improve heat exportation. As a result, this research has developed a novel solar PV/LHP heat pump …
