Experimental and numerical investigation of impinged water jet effects on heated cylinders for convective heat transfer
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2019)Effect of jet flow structures impinged on a heated cylinder has been investigated experimentally and numerically in this study. The FLUENT 6.3.26 was used to simulate this numerical problem. In the numerical section, the ... -
Experimental and theoretical studies for mild steel corrosion inhibition in 1.0 M HCl by three new quinoxalinone derivatives
(ELSEVIER SCIENCE BV, 2016)Three quinoxalinone derivatives, namely (E)-3-styrylquinoxalin-2(1H)-one (SQ), (E)-3-(4methoxystyryl)quinoxalin-2(1H)-one (MOSQ) and (E)-3-(4-methoxystyry1)-7-methylquinoxalin-2(1H)-one (MOSMQ) were synthesized and ... -
An Experimental Approach for Understanding V-I Characteristic of Electric Arc Furnace Load
(KAUNAS UNIV TECHNOLOGY, 2017)Electric Arc Furnaces (EAF) are nonlinear loads causing power quality problems on the systems they are connected to. The main reason of EAFs causing power quality problems is the nonlinear characteristics of the electric ... -
Experimental characterization of the impact-damage tolerance of a cross-ply graphite-fiber/epoxy laminate
(WILEY, 2008)In this study, the impact-damage tolerance of a graphite-fiber/epoxy composite laminate is studied by examining the correlation between the impact force and the resulting delamination area in the laminate. The crossply ... -
Experimental determination of interfacial energy for solid Al in the Al-Sn-Mg eutectic system with Bridgman-type apparatus
(ELSEVIER SCIENCE BV, 2019)The equilibrated grain boundary groove shape of solid Al in equilibrium with Al-Sn-Mg eutectic liquid was observed by using a Bridgman type directional solidification apparatus. The ratio of the thermal conductivity of the ... -
Experimental evaluation of using various renewable energy sources for heating a greenhouse
(ELSEVIER SCIENCE SA, 2013)The interest in alternative or renewable energy sources for greenhouse heating is currently high, owing to the large heating loads and the relatively high price of fossil fuels. Important alternative sources of energy are ... -
Experimental hot-wire measurements in a centrifugal compressor with vaned diffuser
(ELSEVIER SCIENCE INC, 2008)The purpose of this study was to improve the understanding of the flow physics in a centrifugal compressor with vaned diffuser. For this reason three component hot wire measurements in the vaneless space and vane region ... -
Experimental investigation of mixed convection heat transfer in a rectangular channel with discrete heat sources at the top and at the bottom
