Selected papers presented during the International Scientific Conference on Numerical Heat Transfer (NHT2005). The papers demonstrate, on one hand, an overview of the conference topics and, on the other hand, to document the most important advances in numerical heat transfer.
Contents:
Numerical simulation of complex transport phenomena arising in practical thermal systems
This paper seeks to discuss the numerical modeling of the transport processes that frequently arise in practical thermal systems and involve complexities such as property variations with temperature or with the shear rate in the flow, complicated regions, conjugate mechanisms, chemical reactions and combined mass transfer, and intricate boundary conditions.
Verification of a numerical model of macrosegregation in direct chill casting
This paper aims to point out the critical problems in numerical verification of solidification simulation codes and the complexity of the verification and to propose and apply a procedure of generalized verification for macrosegregation simulation.
Finite element modelling of the squeeze casting process
This paper sets out to present developments of a numerical model of squeeze casting process.
Numerical analysis and experimental validation of the free surface flow and heat transfer in electrical transformers moulding processes
The purpose of this paper is to present a numerical and mathematical model of a moulding process of a dry electrical transformer. Moreover, the calculated results are reported and compared with experimental measurements.
Thermocapillary convection and phase change in welding
In welding there is an intricate coupling between the composition of the material and the shape and depth of the weld pool. In certain materials, the weld pool may not penetrate the material easily, so that it is difficult or impossible to weld, while other seemingly quite similar materials may be well suited for welding. This is due to the convective heat transfer in the melt, where the flow is driven primarily by surface tension gradients. This paper aims to study how surface active agents affect the flow and thus the welding properties by surveying some recent 3D simulations of weld pools.
Temperature in a disk brake, simulation and experimental verification
This paper seeks to develop a reliable simulation technique and experimental equipment applicable to thermal analysis of disk brakes. The application is focused on safety issues arising in coal mines and other hazardous explosive environments.
An evolutionary-based inverse approach for the identification of non-linear heat generation rates in living tissues using a localized meshless method
This paper aims to develop and describe an improved process for determining the rate of heat generation in living tissue.
Computation of radiative transfer in combustion systems
This paper seeks to review the literature on methods for solving the radiative transfer equation (RTE) and integrating the radiant energy quantities over the spectrum required to predict the flow, the flame and the thermal structures in chemically reacting and radiating combustion systems.
Optical tomography with the equation of radiative transfer
This paper sets out to give an overview about state-of-the-art optical tomographic image reconstruction algorithms that are based on the equation of radiative transfer (ERT).
Natural convection in partially porous media: a brief overview
This paper aims to provide a limited, but selective bibliography on modelling heat and mass transfer in composite fluid-porous domains.
Multidimensional modeling of two-phase flow and heat transfer
This paper seeks to discuss a mechanistic modeling concept for local phenomena governing two- and multi-phase flows and heat transfer.
Boundary element method for thermal flows using k-? turbulence models
This paper aims to develop a multidomain boundary element method (BEM) for modeling 2D complex turbulent thermal flow using low Reynolds two-equation turbulence models.
Analysis of macroscopic momentum equation in a columnar mushy zone
This paper aims to tackle the problem of some ambiguity of the momentum equation formulation in the commonly used macroscopic models of two-phase solid/liquid region, developing during alloy solidification. These different appearances of the momentum equation are compared and the issue is addressed of how the choice of the particular form affects velocity and temperature fields.
Numerical study of turbulent channel flow with strong temperature gradients
This paper sets out to perform a detailed numerical study of turbulent channel flow with strong temperature gradients using large-eddy simulations.
