%X two-phase heat transfer involving two immiscible systems is gaining importance in petrochemical and allied industries. varying compositions of diesel and water were experimentally studied in a 1:2 shell and tube heat exchanger. the data on pure water and diesel were fitted to an equation of the form. h1¦Õ = a nmre.the two-phase multiplier, ¦Õ l, was related to the lockhart martinelli (l-m) parameter, ¦Ött2, using the two-phase data and a correlation ¦Õ l = b+c(¦Ött2)+d/(¦Ött2)2 was established. the two-phase heat transfer coefficient was calculated based on the coefficients 'a' and 'm' for pure diesel and pure water along with §æl and the l-m parameter. the calculated values of the two-phase heat transfer coefficient h2¦Õ based on pure diesel and pure water suggest that diesel is a better reference fluid since the average error is much smaller compared to pure water as reference.
