Lecture

Thermal Analysis of Foundry: Chvorinov Theory

Description

This lecture delves into the thermal analysis of foundry processes, focusing on Chvorinov's theory. It covers the analytical expressions for position and temperature profiles, energy balances at interfaces, and the interpretation of key parameters. The lecture also explores the relationship between temperature, speed, and position of the solidification front, as predicted by Chvorinov's model. Additionally, it discusses heat flow, equilibrium equations, and the determination of parameters for successful solidification. The lecture concludes with a detailed examination of the solid-liquid interface, energy balances, and the control of solidification rates in foundry processes.

Heat transfer

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species (mass transfer in the form of advection), either cold or hot, to achieve heat transfer.

Heat exchanger

A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment.

Heat sink

A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature. In computers, heat sinks are used to cool CPUs, GPUs, and some chipsets and RAM modules.

Heat pipe

A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid, releasing the latent heat. The liquid then returns to the hot interface through capillary action, centrifugal force, or gravity and the cycle repeats.

Thermal analysis

Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature.
