Abstract

An approximate solution is obtained using a finite element method to solve the equation of motion governing the steady state, fully developed, incompressible Newtonian flow within a straight tube with internal fins. The values of the product f Re are computed over a wide range of values for length, thickness and number of fins. It is observed that equivalent diameter alone is not a sufficient parameter to correlate f Re values. The equation. fRe = -0.5077 + 16.287( De Di)1.2 -0.049 ×. {1-exp( 20sl s+l)}. predicts f Re values with an average error of 2.0%. A less rigorous correlation in terms of De/Di alone is given by. f Re = 16.07 (De/Di)1.177. This equation predicts f Re values with an average error of 4.0%.
