In this paper, numerical analysis of conical shell (Continuous decreasing annulus space) heat exchanger has been made considering different Nusselt number correlations for annulus flow. The inner tube is considered cylindrical and the outer shell has three shapes as cylindrical with diameter ratio 1, conical with a diameter ratio of 0.882 and conical with a diameter ratio of 0.765. Water flows through the inner pipe at a constant flow rate of 10 LPM whereas the flow rate of water in outer shell varies from 10 LPM to 20 LPM. Heat transfer coefficients for inner flow and outer flow have been calculated considering different Nusselt number correlations. The calculation has done for overall heat transfer coefficients for all cases and results of conical shapes compared with a cylindrical shape. Results reveal that overall heat transfer coefficient increases up to 11 % in a conical shell having a diameter ratio of 0.882 and 26 % in a conical shell having a diameter ratio of 0.765.
