Fluent uses the Gas constant [J \/ kg \/ K], Universal Gas constant is the general gas constant [J \/ Kmol \/ K]. Note the different dimensions: Gas constant is the Universal Gas constant divided by the molecular weight of the specific gas. The Universal Gas constant in Fluent is defined as 8314.34 [J \/ Kmol \/ K].<\/p>\n
