Measurement and prediction of evaporator shell-side pressure drop

As a further step, a new suggested procedure is presented, which extends the Wills and Johnston [Wills MJN, Johnston D. A new and accurate hand calculation method for shellside pressure drop and flow distribution. 22nd National Heat Transfer Conference, HTD N. 36. New York: ASME; 1984, p. 67-79] method to the low Reynolds number range and improve its capability to predict experimental data.
