The dynamics of engine spark ignition are complex, and scientists usually need months to accurately simulate. Now, scientists at the Argonne National Laboratory of the United States Department of Energy (DOE) are using a new software model to study this dynamics more quickly, integrating this new model into a computational fluid dynamics software package used in industry Highly complex processes in internal combustion engines. Automotive engineers hope to seek engines that can significantly improve fuel economy and meet future emission standards by predicting and controlling the cyclic changes within the engine. The new model will greatly reduce the calculation time required for advanced engine simulation, and the simulation calculation time for hundreds of consecutive engine cycles can be shortened from 2-3 months to 10 days.
The new model aroused the interest of a company focused on computational fluid dynamics (Convergent Science), and the two parties will cooperate to integrate it into the company's flagship software product, CONVERGE. The project lasted two years and was funded by the US Department of Energy's Small Business Preferential Program. The plan aims to overcome the key technical challenges facing the US Department of Energy National Laboratory and US small businesses. The project software integration test was successfully completed in June last year. This collaboration has led to a unique capability development that has the potential to greatly benefit engine OEMs by significantly speeding up the turnaround time of engine design.
The project also produced two publications on the subject co-authored by researchers from both parties, reflecting the high-quality interaction between partners. This is a successful example of technology transfer and cooperation between national laboratories and industrial companies. Argonne National Laboratories has been looking for this partnership. This partnership network will ultimately bring benefits to consumers and accelerate cleaner, More fuel-efficient technologies enter the market and realize social benefits.
The study was funded by the Department of Energy ’s Office of Energy Efficiency and Renewable Energy through its Office of Vehicle Technology.
Bismuth is the impurity which is the most difficult to remove during fire refining of crude lead. lead fire process refined debismuthizing agent is prepared and produced by Luanchuan Hengkai Metallurgical Materials Sales Co., Ltd after research and development for many years. The lead fire smelting novel copper removing agent is prepared and produced by our company. After the copper removing agent produced by our company is used, the copper content in the lead after copper removal is within 0.0002. More importantly, after the copper removing agent produced by our company is used, no pollution is produced (no smoke), the emission of sulfur dioxide is reduced, there is no low-altitude pollution, the operation is simple for workers, the operating environment is improved, and free technical guidance is given for the first-time use.
(In addition, our company is specialized in the production of `Hengkai Metallurgical" Brand - Ferro sulphur series for foundry, copper removal agent series for lead smelting, debismuthizing agent for lead smelting, iron sulphide series for resin grinding wheel abrasive industry, iron sulphide series for brake pad friction industry, iron sulphide series for heavy metal wastewater treatment, iron disulphide series for soil improvement, iron disulphide for lithium battery anode, alloy sand series for wear-resisting flooring industry, ferrous sulphide powder series for ferrous sulphide cored wire, ferrous sulphide for ferrous sulphide cored wire, iron sulphide for resin grinding wheel, ferrous sulphide powder for heavy metal wastewater treatment, ferrous sulphide powder for soil improvement, ferrous sulphide cored wire, pyrite, ferrous sulphide ore, molybdenum oxide, high purity molybdenum trioxide, ammonium molybdate, titanium dioxide, cryolite powder, mullite, etc.)
