The flow in a helical intake port of a direct injection diesel engine is analyzed by a modified version of KJVA-II code. The computational grid is generated by direct interface with a three dimensional CAD data for the<br/> complicated port shape. Results show that the flow structure in a stea dy state flow rig for swirl measurement can be quite different from that in an<br/> actual engine. Although the swirl ratio may be the most important<br/> parameter characterizing the cylinder flow. the techniques such as optical flow measurement and 3-D computational simulation should be used for other flow details.<br/>

The recent trends in numerical simulation of various spray phenomena are reviewed in this article. Major subtopics are atomization/breakup, collision/coalescence, wall collision, interfacial transfer, droplet dispersion, two-phase injection and spray combustion. Each submodel has been under continuous refinement and validation against more extensive data base by advanced laser diagnostic techniques. Most uncertainty in current spray simulations come from these physical submodels, not from excessive computational constraints.
