Combustion marks its existence since Stone Age period in form of mere fire and since then this phenomenon has played a major role in evolution as well as revolution of mankind. Right from its mediocre application of providing light and warmth to its sheer brilliant use for rocket propulsion for space expedition, combustion has done it all. The major applications of combustion being its use in boilers, gas turbines, automotive, rockets etc, the focus of this blog is to give an insight on combustion in internal combustion engines used for automobiles.
We all must have heard about the term ‘Cavitation’ sometime, more certainly if we have dealt with pumps or similar fluid application and probably might have also seen some effects of ‘Cavitation’. Cavitation is very common term in engineering domain especially if we are dealing with fluids. So let us have a detailed insight into this ‘Cavitation’ phenomenon through this blog.
Imagine you are working as a CFD Analyst/ Design Engineer in a leading automotive industry performing year round optimization studies on various aerodynamic aspects of car design. Definitely your job profile would be exciting and challenging but at the same time most of your tasks involve repetitive CFD procedures like same simulation strategy for various design changes. For such an CFD engineer automation and customization would be a great savior.
Computer Aided Engineering (CAE) is fast becoming an essential ingredient in any engineering design process. Be it product modeling, process analysis or virtual prototype, CAE technology in various form appears throughout engineering industry. Most of the current engineering products and services are first vitalized on computer. CAE field as a technology is evolving and its application horizons constantly expanding.
The particulate emissions from process industries has received great attention due to the upcoming strict environmental protection agency (EPA) regulations and conservation in recent years. The Electrostatic precipitators (ESP) since its development in 1907 by Frederick G. Cottrell (Professor of chemistry at the University of California, Berkeley) have been the most common, effective and reliable technologies for removal of hazardous emissions like flue gases, acid droplets and fine particles.
We all have seen the rain drops falling on roof tops or road or car roofs, or water droplets falling from tap. When we usually see these phenomenons occur around us they happen within no time. We don’t even notice them. But if we look closely there are very complex physics involved in them. What if we could really slow down time and observe closely these phenomenon occurring? Like this video from Discovery Channel which shows a slow motion capture of a droplet falling into a liquid surface.
Are you a CFD engineer? Have you ever faced trouble doing meshing because of CAD issues like complexity in CAD model and CAD data loss while importing CAD geometry in CFD tools? Do you want to know how to do CAD repair and how to get geometry ready for analysis? Its necessity, process and how to do CAD-Repair? Being a CFD analyst do you want to know how to extract CFD domain and how to simplify the task of creating good quality mesh that is required for CFD analysis?
Computational fluid dynamics (CFD) when saw its development on the peak, was meant to merely validate simulations with the experimental results. But the recent trends have shown that confidence in CFD has grown and its use is on the rise to simulate physics problems which have very limited experimental data for its validation. Combustion is one such field where application of CFD and this recent trend has proved to be a boon.
Having the basic introduction to writing a UDF from the earlier article "Writing a UDF for CFD Modeling" wherein we saw using UDF for inserting custom boundary profiles, we shall now see another application of UDF with an example of boiling phenomenon. To get the most understanding from the current article the reader should be familiar with ANSYS Fluent software and basic UDF understanding.
