TLDR
In this article, a numerical study on the transient heating of a cast iron slab in a car-hearth furnace is presented, where the influence of the direction of jets issuing from the burners on the velocity and temperature fields during the heating period was investigated.Abstract:
A numerical study on the transient heating of a cast iron slab in a car-hearth furnace is presented. The influence of the direction of jets issuing from the burners on the velocity and temperature fields during the heating period was investigated. The standard k-e turbulence model is used in the present study. It is found that the direction of the jets has a significant influence on the temperature distribution in the slab. It is also shown that inclined jets produce a more uniform temperature field and that the time needed for the slab to reach a predetermined temperature can be significantly reduced which results in the reduction of energy consumption.read more

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.

Prediction of furnace heat transfer with a three-dimensional mathematical model
TL;DR: In this article, the case of the International Flame Research Foundation (IFRF), Holland, was used to test the performance of a rectangular furnace with a tunnel burner operating on natural gas, firing parallel to the hearth as well as inclined to it.
