Catalytic ignition of CH4, CO, and H2 oxidation on platinum and palladium at atmospheric pressure is studied numerically. Two simple configurations are simulated: the stagnation flow field over a catalytically active foil and a chemical reactor with a catalytically active wire inside. The simulation includes detailed reaction mechanisms for the gas phase and for the surface. The gas-phase trans...

In this paper, a review of some techniques proposed in the literature for modelling fretting wear is presented. Fretting wear occurs when surfaces are degraded and materials are removed due to a small relative oscillatory motion between two contact surfaces. Due to the continuous change in the shape of a structure during its lifetime, the design of engineering components subjected to fretting w...

In 1994, ASHRAE began developing a guideline for measuring retrofit savings (GPC-14P). In support ofGuide­ line-14p, ASHRAE initiated RP-1050 to develop a toolkit for calculating linear, change-point linear, and multiple-linear inverse building energy models. The resulting Inverse Model­ ing Toolkit (IMT) can be usedaspart ofaprocedure to measure savings. This paper describes the numerical algo...
