Experimental Study of Endwall Heat Transfer in a Linear Cascade

Experimental Heat Transfer Study of Endwall in a Linear Cascade with IR Thermography

“…Knowing the heat transfer mechanisms involved can lead to predict accurately the maximum temperature or thermal load on the surface of this component, and therefore, estimate the cooling if needed or select a lighter material that can handle the predicted thermal loads without melting or being sensitive to creep. This work is a continuation of previous investigation in a large-scale linear cascade performed at Chalmers University of Technology [7], [8]. An additional motivation for this work is the comparison between the experimental results using two different heat transfer measurement techniques.…”

Heat exchanger operation in the externally heated air valve engine with separated settling chambers

“…Settling chambers are widely used in analysis of flows, from sound pipes, as analysed at low speed by Erdem et al [6], through cavitation effects in crossflows presented in Chemloul's paper [7], nozzle effects with entropy noise discussed in Leyko et al [8], or sound generation in Kings et al [9]. The heat exchange aspects with estimation of the Reynolds and Nusselt numbers are discussed in Wang et al [10]. The supersonic wind tunnels and turbine devices with settling chambers are of wide interest to many researchers e Bhoi and Suryanarayana [11] attempted to predict the pressure characteristics, Rajani et al [12], discussed temperature effects in testing aerodynamic forces, Silva et al established a model for the Reynolds number test, [13].…”
