This can be accomplished by using acoustic panels with... COMSOL Conference 2010, Boston J.S. Crompton¹ , L.T. Gritter¹ , S. Yushanov¹ , K.C. Koppenhoefer¹ , and D. Magyari² ¹ AltaSim Technologies, LLC, Columbus, OH, USA ² Golden Acoustics, Detroit, MI, USA
	Analysis of Burning Candle Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection... COMSOL Conference 2010, Boston J.S. Crompton, L.T. Gritter, S.Y. Yushanov, and K.C. Koppenhoefer AltaSim Technologies LLC, Columbus, OH, USA
	Analysis of Lubricant Flow Through Reynolds Equation Reynolds equation is used to analyze fluid flow through small gaps. As such, the solution of Reynolds equation provides critical information for a wide range of tribological problems. In any case where a lubricant resides between two...
