Numerical Analysis of a Helical Coiled Heat Exchanger using CFD

Heat exchangers are the important equipments with a variety of industrial applications including power plants, chemical, refrigeration and air conditioning industries. Helically coiled heat exchangers are used in order to obtain a large heat transfer area per unit volume and to enhance the heat transfer coefficient on the inside surface. This paper deals with the CFD simulation of helical coile...

Thermal-Economic Optimization of Shell and Tube Heat Exchanger by using a new Multi-Objective optimization method

Many studies are performed by researchers about Shell and Tube Heat Exchanger but the Multi-Objective Big Bang-Big Crunch algorithm (MOBBA) technique has never been used in such studies. This paper presents application of Thermal-Economic Multi-Objective Optimization of Shell and Tube Heat Exchanger Using MOBBA. For optimal design of a shell and tube heat exchanger, it was first thermally model...

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...

Validation of Plate Heat Exchanger Design Using Cfd

Heat exchanger is an essential device used in complex engineering systems related to heat transfer processes in many industrial applications. Plate Heat Exchanger (PHE) is an important part of a condensing or evaporating system. Among many of factors which should concentrate on, the heat transfer and pressure drop is most important part during sizing and rating the performance of PHE. Due to th...
