Analysis of Unsteady Airfoils at Low Speeds
In this study exemplary results on the influence of two fundamental unsteady parameters, the reduced frequency k and the non-dimensional pitching rate α+, on the transition from a steady to an unsteady flow field around the reference airfoil BAC3-11/RES/30/21 are presented using experimental and numerical techniques. The tools used are described and their results verified with each other. On th...
متن کاملReset Noise at Low Temperatures
This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...
متن کاملCFD Modeling Study of High Temperature and Low Oxygen Content Exhaust Gases Combustion Furnaces
This paper reports a CFD modeling study on the possibility of using high temperature and low oxygen content exhaust gases as oxidant for combustion in an industrial furnace by a written computer program. Under these conditions,the predicted results for the flow and heat transfer properties are compared with those under the several cases of conventional and highly preheated...
