Abstract:  
Pool boiling heat transfer coefficient has been found to improve by 12 to 33% in case of cupro nickel tubes after the outer surface was peened with C.I. grits of G-25 size. Similar treatment on admiralty brass tube resulted improvement of heat transfer coefficient of 11 to 32%. Peening treatment on the surface of condenser tube, thus, shows a good promise for increasing heat transfer coefficients.
