Presentation of heat transfer enhancement results for 1EHT bundle boiling over a wide range of conditions is being presented on October 1, 2013 at PRES’ 13 – the 16th Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction.
Results for the 1EHT bundle show combined overall bundle increases of shellside and tubeside heat transfer up to 97% when compared to the heat transfer enhancement of a smooth tube bundle using typical fluids ( n-Pentane, p-Xylene and water); for midpoint shellside Reynolds number values in the range of 2800 to 20400; with effective mean temperature difference (EMTD) values between 15.4 OF ( -9.2 OC) and 118.3 OF ( 47.9 OC). Enhanced heat transfer tube bundles that are capable of producing efficiency increases in excess of 90% are important options to be considered in the design of high efficiency processes.
