Heat Transfer has special importance in engineering applications. So, researchers have suggested different new idea to increase heat transfer and using nanofluid is one of these methods In recent years, new methods have been used. One of these methods is the use of nanofluids, ., because nanofluids have higher heat transfer potential than base conventional fluids. In this investigation effect o...

This study computationally investigates the heat transfer characteristics in a double-pipe counter-flow heat-exchanger. A heated viscoelastic fluid occupies inner core region, and outer annulus is filled with colder Newtonian-Fluid-Based Nanofluid (NFBN). mathematical model developed to conjugate exchange properties from hot NFBN. The modelling formulation of given problem comprises system coup...

During crystallization the control and effective distribution of heat transfer from the solution to the heat exchanger (HE) plays an important role. Inhomogeneity in temperature on the HE-surface limits the production capacity and increases the tendency of an isolating scale layer formation. To avoid scaling, scraper blades on the HE are commonly used. In a typical axi-symmetric geometry the sc...

A-Type heat exchangers are used to meet required heat load with minimum duct dimensions in air-conditioning applications. This greatly reduces the air-conditioning system footprint in residential and commercial applications. The angle and tube spacing of the A-type heat exchangers should be optimized for minimum duct size and maximum heat load. However, existing air side heat transfer and press...

This paper details the selection of machine learning models for predicting effectiveness a heat pipe system in concentric tube exchanger. Heat exchanger experiments with methanol as working fluid were conducted. The value angle varied from 0° to 90°, values temperature 50 °C 70 °C, and flow rate 40 120 litres per min. Multiple conducted at different combinations input parameters was measured ea...
