A model was developed to predict the formation of austenite and dilatometric behavior during continuous heating in AISI 1045 steel, which has an initial microstructure composed of ferrite and pearlite. The model is proposed in two parts based on the heating rate and steel behavior to estimate the volume fraction of austenite during continuous heating. The first part of the transformation model is...
The present work shows the results of a numerical simulation, in the transient 3D state, of heating a block of stainless steel AISI 304 in continuous movement in the interior of an experimental vertical furnace. The model considers the heat transfer by radiation between the furnace walls and the surface of the block using the model P-1, implemented in CFD Fluent® commercial software. The thermal boundary...
In this work, by numerical simulation using a commercial CFD (computational fluids dynamics) code, were obtained the velocity fields and thermal fields, inside of an indirect type natural convection solar food-dryer. For validating the numerical simulation, was developed an experimental model of an indirect type natural convection solar food-dryer. The food-dryer was instrumented with thermocouples...
