Abstract
In this work, an experimental study is carried out to study the pressu re drop of a thermodependent Iron newtonian fluid flowing in a circula r tube heated with a constant heat flux density. The working fluid use d is a 3% by weight aqueous solution of carboxymethylcellulose, a mode l of many pseudoplastic fluids currently encountered in many process i ndustries. Its rheological behaviour is governed by an Ostwald law tau = K gamma(n) where the consistency K is highly temperature dependent. The results obtained are compared with numerical results and the agre ement is shown to be good.
