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.
Details of the study titled “Evaluation of a 1EHT Enhanced Heat Transfer Tube Bundle for Processes Involving Boiling” will be presented at the 6th Conference Process Integration, Modeling and Optimization for Energy Saving and Pollution Reduction, and published in Chemical Engineering Transactions, Vol 35, 2013.
Utilization of enhanced heat transfer tubes is an effective method used in the development of high performance thermal systems. Vipertex® enhanced surfaces, have been designed and produced through material surface modifications, which result in flow optimized heat transfer tubes that increase heat transfer.
