Two-phase experimental heat transfer studies on a water-diesel system in a shell and tube heat exchanger

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. h1φ = a NmRe.The two-phase multiplier, Φ L, was related to the Lockhart Martinelli (L-M) parameter, χtt², using the two-phase data and a correlation Φ L = b+c(χtt²)+d/(χtt²)² was established. The two-phase heat transfer coefficient was calculated based on the coefficients 'a' and 'm' for...
