Events: Vehicle Thermal Management Demonstration at JSAE 2004
Posted Thu May 13, 2004 @01:12PM
Print version Email story Tweet story
News Flowmaster Group in partnership with CRC Solutions Corporation, Flowmaster’s value added reseller in Japan, will be giving a series of demonstrations on simulating the thermo-fluid dynamic aspects involved with vehicle thermal management.

Taking place on Stand 26 in the IT & software zone the demonstrations will focus on the need to simulate the thermal interactions between the under hood fluid systems found in the vehicle. Such systems include: engine cooling, lubrication, under hood airflow and air conditioning.

“Of particular importance is the packaging of the cooling pack. With Space in the engine bay at a premium, heat exchangers such as the radiator, oil cooler and air conditioning condenser often overlap each other. As a consequence the component with the most overlapping, experiences airflow at a higher temperature than desired, which can impair the performance of the system it resides in” – explains Paul Burns, Automotive Product Manager, Flowmaster Group.

Two Phase (Liquid and Gas) Problem
Posted Thu May 13, 2004 @01:12PM
Print version Email story Tweet story
Help Desk I need help in solving a two phase problem. I have a closed box that is half filled with liquid and has ullage space(with air) above it. I am using CFD-ACE to model flow and heat transfer. What is the most appropriate way to solve this? I tried to use VOF, but it requires a very small time step which is not feasible for my problem. Also, the two-fluid module does not seem to work in conjunction with the heat transfer module. I also tried just flow and heat transfer (without vof or two-fluid models) by making two separate domains and assigning different properties. It doesnt seem to work either. Can anyone suggest what to do here?

Thanks in advance

Application: Reducing Infiltration Through Cold Store Entrances
Posted Tue May 11, 2004 @10:52AM

Application By Alan Foster,
Food Refrigeration and Process Engineering Research Centre (FRPERC),
University of Bristol, UK

Ingress of warm moist air during cold-store door opening is a major issue in refrigeration plants, as it increases energy consumption and can also cause an undesirable rise in product temperature. Moisture infiltration itself can produce food safety problems in chill stores and can jeopardize personnel safety in frozen stores as the moisture turns to ice.

The British Department for Environment, Food and Rural Affairs (DEFRA) has commissioned the University of Bristol (FRPERC) to look at this problem in partnership with Anglo Dutch Meats (UK) Ltd; ACS&T Wolverhampton Ltd., Thermoscreens Ltd., Northern Foods Plc and Ballymoney Foods Ltd. The aim of the project, which is part of the LINK programme, is to reduce infiltration through doorways and thereby reduce the effects on temperature control, safety and energy consumption.

Events: Engine Cooling System Simulation Workshop
Posted Fri May 07, 2004 @04:20PM
Print version Email story Tweet story
News Flowmaster & Fluent announce a free half day workshop focussing on the simulation of engine cooling systems.

This half day workshop is aimed at engineers and engineering managers responsible for system level and component level design decisions.

The workshop will take place on the 18th of May in Detroit. A keynote presentation will be given by Ken Singh, Aero & Fluid dynamics manager, DaimlerChrysler, on the need to co-simulate between 1D & 3D CFD for engine cooling system design.

Following the keynote presentation will be technical sessions on Flowmaster and Fluent capabilities for engine cooling system design and a demonstration of a co-simulation case study of an engine water jacket.

Places are limited so to reserve a place contact Sudhi Uppuluri on 001 734 779 1898 or email

Please note: the workshop date was incorrectly listed as May 14th originally and has been changed. - Editor

News NAFEMS, The International Association for the Engineering Analysis Community, is currently working on expanding its North American Chapter. With some 700 member companies worldwide, the organization is the only truly independent authority on the use of computer modelling and simulation methods, and is widely respected throughout the analysis world.

To this end, the NAFEMS North American Chapter will be holding meetings in a number of locations over the coming period. Many senior individuals from major corporations and vendors, as well as analysis specialists have already asked to be involved, and will be attending these meetings. We extend an open invitation to all interested parties to attend.

The first of these meetings will take place in the Marriott Suites, Anaheim, California on Wednesday 19th May 2004.
