RESEARCH NOTE ON A PARABOLIC HEAT-BALANCE INTEGRAL METHOD WITH UNSPECIFIED EXPONENT: AN ENTROPY GENERATION APPROACH IN OPTIMAL PROFILE DETERMINATION
heat-balance integral method parabolic profile unspecified exponent
2009/10/14
The heat-balance integral method of Goodman is studied with two simple 1-D heat conduction problems with prescribed temperature and flux boundary conditions. These classical problems with well known e...
Vapor-Liquid Equilibrium Modeling of Associated Systems using a Linear Solvatochromic Approach
Vapor-liquid equilibria Associated system Modified LSER model
2009/10/13
A modified linear solvation energy relation (LSER) has been proposed to estimate the properties and vapor-liquid equilibria (VLE) of associated systems. The model combines the solvatochromic parameter...
