WebThe Colburn Factor Using Chilton Colburn Analogy formula is also called Modified Reynolds Analogy. Validity of this analogy depends upon property of fluid and length of plate and is represented as j H = Nu /(Re)*(Pr)^(1/3) or Colburn's j-factor = Nusselt Number /(Reynolds Number)*(Prandtl Number)^(1/3).The Nusselt number is the ratio of … WebThe j factor or Colburn jH factor or the Colburn-Chilton j factor is a dimentionless factor for heat transfer that was first proposed by Prof. Colburn. It is defined by the equation jH = (h/cp. G). Pr^2/3 ………….. (1) Where h = local heat transfer coefficient G = mass velocity of fluid stream Pr = Prandtl number, a dimensionless number defined by
