STUDY ON HEAT TRANSFER EFFICIENCY PARAMETRES IMPROVEMENT IN SYSTEMS or UNITS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 7
Abstract
Heat exchangers are an important component in many industrial systems especially in process industries. So many commercial types of heat exchangers are available in market for exchange of heat as well as for recovery of waste heat. Improved heat transfer efficiency leads to decrease in energy consumption which then results in lower equipment operational and maintenance cost, lower emissions, and consequently also lower environmental impact. However, common enhancement approaches such as adding fins or tube inserts may not always be suitable or feasible – especially in case of heat recovery from streams having a high fouling propensity. Since heat transfer rate depends also on flow field characteristics, fluid distribution, and fouling which can all be greatly influenced by the actual shapes of flow system components, several simplified models for fast and accurate enough prediction of fluid distribution as well as applications for shape optimization based on these models were developed. The created applications can then be employed during the design of heat exchange units to improve their performance and reliability.
