Experimental and Numerical Analysis of Flow and Heat Transfer in a Gas-Liquid Thermosyphon Heat Exchanger in a Pilot Plant
A numerical and experimental investigation of flow and heat transfer in a gas- liquid Thermosyphon Heat Exchanger "THE" with built in heat pipes and aluminum plate fins for moderate Reynolds numbers has been carried out. It's module is composed of 6 rows and 15 columns copper pipes with aluminum plate fins with dimensions of 130cm height, 47cm width and 20cm depth. The tubes have been fill...

15 صفحه اولDiscrete Particle Simulation of Granular Flow
Granular materials, which can be either wet or dry and range from nanometers to centimetres in size, are widely encountered in industries and in nature. As with solids, they can withstand deformation and form heaps; as with liquids, they can flow; as with gases, they exhibit compressibility. These features give rise to another state of matter that is poorly understood (Ennis et al., 1994; Jaege...
متن کاملNumerical simulation of a three-layered radiant porous heat exchanger including lattice Boltzmann simulation of fluid flow
This paper deals with the hydrodynamic and thermal analysis of a new type of porous heat exchanger (PHE). This system operates based on energy conversion between gas enthalpy and thermal radiation. The proposed PHE has one high temperature (HT) and two heat recovery (HR1 and HR2) sections. In HT section, the enthalpy of flowing high temperature gas flow that is converted to thermal radiation em...
متن کاملReview Heat Exchanger: Research Development of Self-rotating Inserts in Heat Exchanger Tubes
Heat exchangers are widely used in power engineering and industrial applications, many techniques such as coiled tube, surface tension devices, rough surfaces, extended surfaces have been investigated to enhancethermal performance and to minimize the cost and size of the heat exchanger equipment. One of the most important techniques is tube insert. In general,tube inserts can be classified into...
