Analysis of Heat Transfer Enhancement in Spiral Plate Heat Exchanger

In the present study, the heat transfer coefficients of benzene in a spiral plate heat exchanger are investigated. The test section consists of a Plate of width 0.3150 m, thickness 0.001 m and Mean hydraulic diameter of 0.01 m. The mass flow rate of water (Hot fluid) is varying from 0.5 kg sec to 0.8 kg sec and the mass flow rate of benzene (cold fluid) varies from 0.4 kg sec to 0.7 kg sec. Exp...

Thermoeconomic Lifecycle Cost Optimization of an Annular Fin Heat Exchanger

In this paper the design of annular fin heat exchanger based on economic optimization has been carried out. The optimization process targeted minimizing the lifecycle cost of annular fin heat exchanger that has the same frontal area, effectiveness and heat load of available practical standard geometry exchangers. The lifecycle cost includes both capital and operating costs. Beside the pumping c...

Heat transfer enhancement in a spiral plate heat exchanger model using continuous rods

This study presents an innovative and simple way to increase the rate of heat transfer in a spiral plate heat exchanger model. Several circular cross-section rods, as continuous vortex generators, have been inserted within the spiral plate heat exchanger in the cross-stream plane. The vortex generators are located at various azimuth angles of α=30◦, 60◦, 90◦, and 120◦ with non-dimensional diame...

Measurement of Flow Field and Wall Temperature Distribution in a Scraped Heat Exchanger Crystallizer

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 HEsurface 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 sca...
