Modern concepts of nuclear reactors cooled with supercritical water are presented together with a short history. The supercritical water-cooled CANDU ((CANada Deuterium Uranium) is a registered trademark of AECL) reactor concept is fully discussed. Also, thermophysical properties at critical and supercritical pressures as well as heat transfer and hydraulic resistance at these conditions are pr...

An important issue in developing a model-based vision system is the speciication of features that are-(a) invariant to viewing and scene conditions, and also-(b) speciic, i.e., the feature must have diierent values for diierent classes of objects. We formulate a new approach for establishing invariant features. Our approach is unique in the eld since it considers not just surface reeection and ...

Ionic liquids have been explored as attractive alternative media for CO2 separation not only due to their low volatility but also due to their highly tuneable nature. Aiming at designing highly efficient liquid phases for flue gas separation and natural gas purification, this work focuses on the use of binary ionic liquid mixtures containing sulfate and/or cyano-functionalized anions. Several m...

43 44 We present a new rough-surface thermophysical model (Advanced Thermophysical Model or 45 ATPM) that describes the observed directional thermal emission from any atmosphereless 46 planetary surface. It explicitly incorporates partial shadowing, scattering of sunlight, 47 selfheating and thermal-infrared beaming (re-radiation of absorbed sunlight back towards the 48 Sun as a result of surfa...

A detailed numerical simulation of forced convection heat transfer occurring in silicon-based microchannel heat sinks has been conducted using a simplified three-dimensional conjugate heat transfer model (2D fluid flow and 3D heat transfer). The micro-heat sink model consists of a 10 mm long silicon substrate, with rectangular microchannels, 57 lm wide and 180 lm deep, fabricated along the enti...
