Research ArticleOpen accessPhrase in the titleFREE CONVECTION OF HEAT TRANSFER IN FLOW PAST A SEMI-INFINITE FLAT PLATE IN TRANSVERSE MAGNETIC FIELD WITH HEAT FLUXP. Geetha, M.B.K. Moorthy, M. DakshinamoorthyA steady two-dimensional MHD free convection of heat transfer in flow past a semi-infinite flat plate in transverse magnetic field with heat flux has been examined. The governing partial differential equation are non-dimensionalised and transformed into a system of nonlinear ordinary differential similarity equations, in a single independent variable η and using Runge-Kutta Gill method with shooting technique. The velocity … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 4 Jul 2014 · 7,059 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleMathematical Model Predicting the Critical Heat Flux of Nuclear ReactorsChien-Hsiung Lee, Lih-Wu Hourng, Kuo-Wei LinBoiling heat transfer system keeps a nuclear power plant safe without getting over-heated. Crisis will occur if the dissipated heat flux exceeds the critical heat flux value. This study assumes the flow boiling system at high heat flux is characterized by the existence of a very thin liquid layer, known as the &#34sublayer&#34, which is trapped between the heated surface … …Journal of Computer Science, Vol. 8, Issue 12 · 12 Dec 2012 · 7,695 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEstablishment, Verification and Application of a Correlation to Predict the Maximum Heat Flux of a Horizontal Closed-Loop Pulsating Heat PipeNiti Kammuang-Lue, Teerasak Hudakorn, Pradit TerdtoonProblem statement: In heat pipe design, it was very important to be sure that the desired heat pipe would not operate in the MHF state. In the case of a vertical CLPHP, the MHF state and maximum heat flux could be predicted by using the correlation, while, in the case of a horizontal CLPHP, there had been no study presented … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,422 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleModeling of Transient Heat Flux in Spark Ignition Engine During Combustion and Comparisons with ExperimentT. F. Yusaf, Sye Hoe, Fong et al.A quasi-one dimensional engine cycle simulation program was developed to predict the transient heat flux during combustion in a spark ignition engine. A two-zone heat release model was utilized to model the combustion process inside the combustion chamber. The fuel, air and burned gas properties throughout the engine cycle were calculated using variable specific heats. The transient heat flux inside … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,173 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleContribution of Advective and Non-advective Heat Fluxes to the Heat Budget of a Shallow LagoonRodríguez-Rodríguez MiguelThe heat budget in a shallow lagoon has been established from field measurements at a bihourly scale. Information on the main advective and non-advective heat fluxes were collected during year 2003 at Nueva lagoon (Almería, Southern Spain). Heat storage data was obtained from a thermistor chain located in the deepest part of the lagoon and meteorological information was acquired using … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,491 accessesView PDF Cite
