Journal ArticleDOI
Performance and exhaust emissions of a gasoline engine with ethanol blended gasoline fuels using artificial neural network
Gholamhassan Najafi,Barat Ghobadian,T. Tavakoli,David R. Buttsworth,Talal Yusaf,M. Faizollahnejad +5 more
TL;DR: In this paper, an ANN model was developed to predict a correlation between brake power, torque, brake specific fuel consumption, brake thermal efficiency, volumetric efficiency and emission components using different gasoline-ethanol blends and speeds as inputs data.
Journal ArticleDOI
CNG-diesel engine performance and exhaust emission analysis with the aid of artificial neural network
TL;DR: In this paper, the authors investigated the use of artificial neural network (ANN) modelling to predict brake power, torque, BSFC, NOx, and exhaust emissions of a diesel engine modified to operate with a combination of both compressed natural gas CNG and diesel fuels.
Journal ArticleDOI
Assessment of effective thermal product of surface junction thermocouples on millisecond and microsecond time scales
TL;DR: In this paper, the response of surface junction k-type thermocouples was investigated experimentally using a water droplet calibration technique (for millisecond times scales) and a small shock tube (for microsecond time scales).
Journal ArticleDOI
Hot-Wall Reentry Testing in Hypersonic Impulse Facilities
TL;DR: In this article, the authors used resistive heating on a carbon-carbon model to preheat the model immediately before conducting a test, which enabled testing at wall temperatures in excess of 2000 K in the X2 expansion tube at the University of Queensland.
Journal ArticleDOI
Radial conduction effects in transient heat transfer experiments
TL;DR: In this article, a simple analytical curvature corrections for heat transfer results inferred on the assumption that flat plate conditions prevailed during the experiment are presented. Buttsworth et al. showed that the curvature correction can be used to account for surface curvature effects in the routine analysis of experimental data.
