Abstract:
A numerical analysis of flow maldistribution and shell side flow on heat in a shell and tube heat exchanger is presented. The flow field at the inlet and in the headers was obtained by solving conservation equations of mass and momentum by employing k-ε turbulence model. As the flow maldistribution in the header affects the heat transfer performance of the STHE, pressure drop and velocity distribution of the fluid inside the header were analyzed. Two types of headers were considered with varying header length for a Reynolds number range of 1000 to 3000. As the header length was increased to 15

Abstract:
Traditionally Shell-and-tube heat exchangers are designed using correlation based approaches like Kern method and Bell-Delaware method. With the advances in Computational Fluid Dynamics (CFD) software, it is now possible to design small heat exchangers using CFD. In this thesis, shell-and-tube heat exchangers are modeled and numerically analyzed using a commercial finite volume package. The modeled heat exchangers are relatively small, have single shell and tube passes. The leakage effects are not taken into account in the design process. Therefore, there is no leakage from baffle orifices and

Abstract:
<p> A common technique to improve the performance of shell and tube heat exchangers (STHE) is by redirecting the flow in the shell side with a series of baffles.

Computational fluid dynamics simulations and experiments were performed to analysis the 3-dimensional flow and heat transfer on the shell side of an STHE with and without baffles. Although, it was found that there was a small difference in the average exit temperature between the two cases, the heat transfer coefficient was locally

Abstract:
Now a days, Shell and tube heat exchanger (STHE) is the best well known a heat exchanger broadly used in oil refinery, and other large chemical process due to fit to very high pressure application. The simulation process comprises of modeling and meshing the geometry of the STHE using CFD package ANSYS 15.0. The aim of the project is to design STHE with respect to heat transfer, flow characteristics, temperature field inside the shell and pressure drop. This is to be investigated by numerically modelling using ANSYS software tools. The heat exchanger (HE) contains 10 tubes inside a 600 mm long

Abstract:
Heating and chemical reactors benefit substantially from the serpentine tube arrangement in a tubular structure. Small space and high heat transfer coefficients may be achieved using the serpentine tube-in-tube design. ' An investigation of the effects of nanofluids, such as Al2O3/water and CuO/water nanofluids, on heat transfer (HT) and efficiency of a serpentine tube heat exchanger is the goal of this study. Modeling in Creo and CFD simulations are carried out using ANSYS's FLUENT software, respectively. When nanofluids are used, shell and serpentine heat exchangers become more e
