In this paper, the effect of adding hydrogen to the composition of methane and air in a micro combustor is investigated by a three-dimensional numerical method. First, the results of the current study in determining the wall temperature of the micro combustion chamber are compared with those obtained from the experimental and numerical results of the previous research. By confirming the numeric...

Catalytic naphtha reforming is one of the most important processes in which, low quality naphtha is converted into high octane motor gasoline. In this study, a mathematical model was developed and was used for investigation the effect of temperature, pressure, hydrogen to hydrocarbon ratio on the octane number, the yield of product and the undesirable phenomena of coke deposition in a semiregen...

This study experimentally investigates the effect of processing parameters on mechanical properties of injection molded copolymer. This paper presents an experimental study on the effects of processing parameters including melt temperature, injection pressure and amount preliminary materials on tensile strength of injection molded copolymer PP-WGRT. Polypropylene (PP - supplied by T.P.C of Iran...

Molecular dynamics (MD) simulations of chloroform vapor and liquid at normal temperature and pressure and liquid under hydrostatic pressure are presented, giving bond lengths and vibrational frequencies as functions of pressure. The change in bond lengths between vapor and liquid at normal temperature and pressure is consistent with a pressure equivalent to the cohesive energy density (CED) of ...
