The effect of the design on heat transfer is numerically investigated by using wavy inner tube in a double-pipe exchanger. A was used to give turbulent fluid along double In numerical study, ANSYS 12.0 Fluent code program used, and basic protection equations were solved for steady-state, 3-D flow conditions. study examined at Reynolds numbers ranging from 2700-5300. obtained results compared wi...

The Department of Energy (DOE), National Energy Technology Center (NETL), has initiated a strategic plan for the development of advanced technologies needed to design and build fossil fuel plants with very high efficiency and environmental performance. These plants, referred to as “Vision 21” by DOE, will produce electricity, chemicals, fuels, or a combination of these products, and possibly se...

the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...

The thermal performance of a heat exchanger is important for the potential application in an integrated solar cell/module and thermoelectric generator (TEG) system. Usually, the thermal performance of a heat exchanger for TEGs is analysed by using 1D heat conduction theory which ignores the detailed phenomena associated with thermo-hydraulics. In this paper, thermal and momentum transports in t...

Three-dimensional CFD simulations are carried out to investigate heat transfer and fluid flow characteristics of a four-row plain fin-and-tube heat exchanger using the Commercial Computational Fluid Dynamics Code ANSYS CFX 12.0. Heat transfer and pressure drop characteristics of the heat exchanger are investigated for Reynolds numbers ranging from 400 to 2000. Fluid flow and heat transfer are s...

Single-phase heat transfer and pressure drop tests were conducted in a tube with two types of twisted tapes. Each tape had exactly similar physical parameters made the same material except that each an opposite twist resulted clockwise anticlockwise flow swirl, i.e., left turn right turn, respectively. type ratio 4 5.5 on 180° twist. The tapes tested tube-in-tube exchanger having 2 m length. in...

In order to improve thermo-hydraulic performance of laminar flow various techniques has been used among which a plain tube with twisted tape insert is widely used. The main objective numerically study field in enhance heat transfer, through circular pipe built with/without Dimples on strip. Effect and dimple strip thermo hydraulic discussed. analysis results for range 800<Re<2000 obtained...

A software for the thermal and hydraulic design of shell and tube heat exchangers with flowinduced vibration checks has been developed in a Windows-based Delphi programming environment. Its user-friendly input format and excellent colour graphics features make it an excellent tool for the teaching, learning and preliminary design of shell and tube heat exchangers. Design methodology is based on...
