Numerical Hydromagnetic Thermal Mechanism in Chemically Reacting Fluid Over a Radiative Melting UPHSR With Resistive Heating

Frontiers in Physics, 2022
Heat transport over an upper paraboloid horizontal surface of revolution (UPHSR) has attracted much interest of the researchers and aero dynamists. The flow of fluid around the pointed surface of rocket, bullets, bonnet, and fighting aircrafts exhibits ...

EFFECTS OF INTRAPARTICLE FLOW ON CATALYTIC REACTIONS

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1974
The effects on solid-catalyzed reaction of intraparticle flow resulting from an axial pressure gradient in a flow reactor are investigated theoretically and experimentally. First, an equation which gives the effectiveness factor under the combined effects of flow and diffusion is presented and the results are compared with experiments using an ion ...

Numerical analysis of reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion [PDF]

, 2009
The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations (DNS) of three-dimensional, turbulent Bunsen flames with reduced methane-air ...

A DNS study of the effects of temperature non-uniformity and turbulence on an auto-ignition process in a homogeneous n-heptane/air mixture

Nihon Kikai Gakkai ronbunshu, 2014
We examine the effects of temperature non-uniformity and turbulence on homogeneous charge compression ignition (HCCI) of a homogeneous n-heptane/air mixture, using three-dimensional direct numerical simulations of the mixture flows.

A Study on the Effect of Flow Unsteadiness on the Yield of a Chemical Reaction in a T Micro-Reactor

Micromachines, 2021
Despite the very simple geometry and the laminar flow, T-shaped microreactors have been found to be characterized by different and complex steady and unsteady flow regimes, depending on the Reynolds number. In particular, flow unsteadiness modifies strongly the mixing process; however, little is known on how this change may affect the yield of a ...
