Abstract The 10MW high temperature gas-cooled reactor (HTR-10) is a modular pebble-bed type reactor, of which the inlet and outlet helium are 250 700 °C, respectively. It reached to its first criticality in December, 2000, operated for nearly twenty years successfully. Currently, HTR-10 only that can operate world. To verify natural circulation operating characteristics safety features passive ...

Wort boiling is the most energy intensive stage in brewing process. Novel wort systems have been explored to reduce primary consumption and improve quality beer flavor stability. Low thermal stress proposed for boiling, but content of dimethyl sulphide (DMS) may exceed required product threshold. A single spinning cone evaporator (SCE) enhance separation DMS minimise wortboiling. The performanc...

When exposed to alpha-difluoromethylornithine (DFMO), an inhibitor of polyamine biosynthesis, Chinese hamster ovary cells become increasingly sensitive to the cytotoxic effects of elevated temperatures (D.J.M. Fuller and E.W. Gerner, Cancer Res., 42:5046-5049, 1982). This sensitization becomes marked at times greater than 24 h after drug removal, and by 48 h, polyamine-depleted cells that have ...

Spray cooling is one of the most promising technologies in applications which require large heat removal capacity in very small areas. Previous experimental studies have suggested that one of the main mechanisms of heat removal in spray cooling is forced convection with strong mixing due to droplet impingement. These mechanisms have not been completely understood mainly due to the large number ...

Recent years have seen a rapid growth of interest by the scientific and engineering communities in the thermal properties of materials. Heat removal has become a crucial issue for continuing progress in the electronic industry, and thermal conduction in low-dimensional structures has revealed truly intriguing features. Carbon allotropes and their derivatives occupy a unique place in terms of th...
