Heat Transfer

Brine water use to flow inside the tubes of a condenser, while been heated by the condensing steam on the outside of these tubes. Fouling are formed on the inside surface of the tubes, acting as thermal insulation, decreasing the thermal efficiency of the system. The essence of fouling influences on the performance of the smooth tube condenser is investigated. Enhanced heat transfer technique is been suggested for use to improve tubing heat transfer performance in MSF system. Enhanced heat transfer surface has a special geometry, provides a higher heat transfer coefficient or a wider surface per unit space area's than a traditional design. Heat exchanger of refrigeration and automotive industries are encountered enhanced heat transfer mechanisms in their applications. Such technique can be used with any heat exchanger. However, each must be tested to see if this particular application makes sense. Unfortunately all current MSF systems are designed using smooth surface tubes, mainly because of the complexity effects of fouled brine water on available heat transfer mechanisms. Enhanced technique and fouling versus heat exchanger have been of interest for a number of years and for a number of researchers. [Kalendar A, Galal T, Al-Saftawi A, Zedan M, Karar SS, et al.
