✦ Synopsis

A theoretical model has been deveIoped to dcscnbe heat transfer to a fluid w&h 1s flowmg turbulently m a prpc and wtthm Wuch a first-order cndothcrnuc lrrcvcrslblc chemical rcactmn 1s takmg place It IS based on the penetration model for the fluid boundary layer close to the pipe wall and enables the calculation of the effect of chemical reaction on the heat transfer coefliclent of turbulent pipe flow The model has been checked agamst expcruncntal results for Row dtstnbuUon and heat transfer m turbulent pipe flow without chemical reaction Good agreement between the calculated and experimental results was found The measured heat transfer coefficients for turbulent pipe flow w~tb a uIuformly dlstnbuted heat source withm the fluid were also well predIcted Unfortunately no accurate cxpcnmental data on the effect of a first-order chcnucal reaction on the heat transfer coeficient of turbulent pipe flow are avmlable However, calculauons made with the model show that 011s effect can be considerable and thus may not always be neglected m practice 1 INTRODUCTlON
