Thermal ignition in a reactive slab with unsymmetric boundary temperatures

modelling the impact of radiative heat loss on co2 emission, o2 depletion and thermal stability in a reactive slab

in this paper, we examine the effects of thermal radiation on co2 emission and o2 depletion in an exothermic reactive slab of combustible materials with uniform surface temperature. the governing equations for the nonlinear heat and mass transfer problem are derived and solved numerically using runge-kutta-fehlberg method with shooting technique. numerical expressions for temperature field, co2...

Emerging geothermometers for estimating slab surface temperatures

A great variety of volatile-rich material is fed into subduction zones, including all sorts of marine sediment, altered oceanic crust and some serpentinized mantle lithosphere1. Subduction delivers these materials to depth, but their subsequent history depends on how pressure and temperature increase together. In the cool shallow subduction zone, !uids are liberated at subsolidus temperatures, ...

Transient Three-Dimensional Thermal Analysis of a Slab with internal heat generation and heated by a Point Moving Heat Source

In this work, analysis of transient three-dimensional heat transfer in a slab with internal heat generation and heated by a point moving heat source along its axis is carried out using integral transforms methods. The heat input into slab or workpiece by the moving heat source is considered in the model. From the results, it was established that the temperature of the material during the heat t...
