MacroFlow

- A Software Tool for Rapid Flow and Thermal Design of Electronics Cooling, Semiconductor Processing, and General Flow Systems

Overview
MacroFlow is a powerful software tool for rapid and accurate flow and thermal design of flow systems in a wide variety of engineering applications. The underlying technique of Flow Network Modeling (FNM) involves representation of a flow system as a network of components and flow paths with overall flow and thermal characteristics. The system behavior is determined through a system-level direct solution of the mass, momentum and energy conservation equations.

MacroFlow for Electronics Cooling
MacroFlow is very well suited for rapid flow and thermal design of a variety of air- and liquid-cooled systems in Computer, Telecom, Defense, and Power electronics applications. The component library in MacroFlow includes many electronics-cooling components such as Fan and Pump, Heat sink, Cold Plate, and Heat Exchanger, Air Filter, Screen, and Quick Disconnect. Since MacroFlow-based analysis is very simple and fast, its use allows determination of a good system design early in the design cycle.

MacroFlow for General Flow Systems
MacroFlow uses the Flow Network Modeling (FNM) technique for a quick and accurate analysis of the thermo-fluid behavior of the entire system that is critical for system-level design. MacroFlow has an intuitive Graphical User Interface (GUI) with an extensive component library and fluid property database, an efficient solution method, and powerful postprocessing capabilities for quick and accurate system-level analysis of a wide variety of gas and liquid flow and thermal systems.


MeltFlow

- A Family of Software Tools for Comprehensive Simulation of the Vacuum Arc Remelting (VAR) and Electroslag Remelting (ESR) Processes

Overview
The Vacuum Arc Remelting (VAR) and Electroslag Remelting (ESR) processes are used for the production of high-quality ingots of superalloys, high-performance steels, and titanium alloys. Due to the complexity of the processes, and high capital investments and operating costs, a trial-and-error based approach for process improvement is very costly.

MeltFlow-VAR
The software tool MeltFlow-VAR utilizes advanced CFD techniques that have been specifically developed for a detailed and efficient analysis of DC electromagnetics, and fluid flow, heat transfer, phase change, and alloy element redistribution phenomena occurring in the VAR process. Hence, MeltFlow-VAR enables a comprehensive, accurate, and efficient analysis of the entire process to predict the pool evolution, and the thermal history, distributions of concentrations of alloying elements, Local Solidification Time (LST), primary and secondary dendrite arm spacings, and freckle formation probabilities in the ingot produced.

MeltFlow-ESR
The software tool MeltFlow-ESR utilizes advanced CFD techniques that have been specifically developed for a detailed and efficient analysis of AC electromagnetics, and fluid flow, heat transfer, and phase change phenomena in the molten slag and the ingot occurring in the ESR process. As a result, MeltFlow-ESR enables a comprehensive, accurate, and efficient analysis of the entire process to predict the slag heating and pool evolution, and the thermal history, distributions of concentrations of alloying elements, Local Solidification Time (LST), dendrite arm spacings, and freckle formation probabilities in the ingot produced.
