Introduction Many ASCI computational problems involve fluid flows interacting with a wide variety of physical and chemical processes including exothermic reactions and particle and energy transport requiring enormous computational resources to model important problems. Common features are found in a variety of reactive flow systems.
Shocked flows are of particular interest.
The following sections develop an example for a simulation center for the design of automotive engines. Any one or a combination of the above subject areas could likewise be used. Engine combustion mirrors the goals of ASCI applications. Both require 3D models, multiphase flows, close interactions between physical and chemical processes, high-end computational resources, more than a million computational nodes, massively parallel computers, and other features as well. Simulation Center for Automotive Engine Design Background Large scale computational modeling of chemically reacting fluid flow in the combustion chambers of diesel and spark-ignition engines has been pursued for more than twenty years, with significant impact on practical engine design.
