Research ArticleOpen accessAll words, across the recordSimulation Studies on A Cross Flow Plate Fin Heat ExchangerM. Thirumarimurugan, T. Kannadasan, E. RamasamyCompact heat exchangers which were initially developed for the aerospace industries in the 1940s have been considerably improved in the past few years. The main reasons for the good performance of compact heat exchangers are their special design which includes turbulent which in turn use high heat transfer coefficient and resists fouling, and maximum temperature driving force between the hot … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,241 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe 2D Eulerian Approach of Entrained Flow and Temperature in a Biomass Stratified Downdraft GasifierA. Rogel, Jasni AguillónThis paper describes a “1-D+2-D” numerical model used to simulate the gasification of pine wood pellets in a stratified downdraft gasifier whereby Eulerian conservation equations are solved for particle and gas phase components, velocities and specific enthalpies. The model takes into account the biomass particle process such as heating up, drying, primary pyrolysis of biomass, secondary pyrolysis of tar, homogeneous … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,257 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA NOVEL ROBUST AND EFFICIENT TOOL FOR DETECTING HETEROSCEDASTICITYWei Xiong, Maozai TianOne of the greatest values of Quantile Regression (QR) is that it provides a good procedure in the sense that QR could be much more efficient and sometimes arbitrarily more efficient in recovering the mean function than the Least Squares (LS) even when without moment conditions. However, heteroscedasticity definitely causes conditional variances of parametric or nonparametric estimates of mean functions … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 21 Mar 2014 · 6,662 accessesView PDFCite
