Numerical Analysis through a Tubular Reactor: Velocity Effect

Abstract

Chemical reactions occur everywhere in our everyday life, for example, in the human body, in cell phone batteries, in a rocket engine and in the pharmaceutical and chemical industry. In this research the model provides a study of an elementary, exothermic, 2nd-order reversible reaction in a tubular reactor (liquid phase, laminar flow regime). The aim of this project is to study numerically the effect of convective Heat and Mass transfer flow of a viscous fluid in the reactor. Assuming that the variations in angular direction around the central axis are negligible makes it possible to reduce the model to a 2D axisymmetric model. The investigation of forced convection flow, heat and mass transfer phenomena through a tubular reactor is carried. The implications of Reynolds number (Re) and Prandtl number (Pr) on the flow structure, heat transfer and mass transfer characteristics are presented. The results are presented in the form of stream functions, isothermal lines, iso-concentrations, surface temperature, arrow plot, average Nusselt number and Sherwood number, mean temperature, average concentration and mean velocity.

Comparative Study between 2D and 3D Modeling of Nanofluid Filled Flat Plate Solar Collector

“…Project or survey reports are also conducted on various types of solar collectors [17][18][19][20][21]. Experimental studies are performed based on solar collectors [22][23][24].…”

Study on numerical simulation of spirality inserted piece for heat exchanger

“…Since the large helical curved surface including the entire tube bundle, which is difficult to manufacture, is simplified into a spiral insert which can be easily manufactured and embedded in each tube. The laminar motion of the fluid on the tube side becomes a number of localized helical turbulent flows [9]. Furthermore, the spirality inserted piece may be formed by twisting an ordinary thin steel sheet, low cost, low energy consumption, and can get a better heat transfer enhancement effect.…”
