Report Prepared

Ultimately I could get simulation results upto time 3 ms from the fuel injection started. On Thursday, 30th June, I presented the results to my investigator. He asked me to make a report on this by 4th July. As I wanted to go to Mumbai to attend Parag's wedding, I had to finish the report on 1st July itself which I did. It was a 16 page report discussing the excercise undertaken for tuning of model constant and the simulation of actual combustor. I emailed it to my investigator and left the lab. The whole work of analysing results, preparing presentation and the report took some seventy hours with two breaks of three-four hours each. But then I was free to enjoy my Mumbai visit.

Read Something About My Reseach This Time!

One will certainly think (if at all anybody has gone through my blog) from my posting last couple of months that this guy writes that he is a doctoral student but shows no signs of being one; does he do some thing for his research project! The other may feel that is he really doing doctorate! Even when I read through

Anyway now I am decided to write at least a few lines about what I have been doing and just yesterday what I have achieved. The word achieved sounds to be quite a big word. May be I should say I should share the results I have obtained yesterday.

Two months back I arrived at some values of model constants in droplet breakup models. Two weeks back we set a case simulating a complete gas turbine combustor for aircraft cruising conditions. We used the methodology which I have made familiar with and the constants I had found out. After some fine tuning we have realised that the simulation has started returning some encouraging results like SMD of 65 micron at the atomiser exit which is close to the experimental value of 60 micron. This is a real time simulation. By saying that I mean, we simulate the the flow when we start injecting fuel at time = zero microsecond and then at interval of every 25 microsecond we find the situation inside the combustor. This we study by taking snapshots of various properties of mixture like fuel species concentration, mixture temperature, concentration of species created after burning starts etc.

As the memory requirement and computations involved is huge, such simulation excercise takes a lot of time to do the calculations. In my case simulate a time step of 25 micro second our computer takes around 45 minutes. At present we have reached to 3.125 mili second. We had a break to take a stock of the situation and to see whether we confirm to the measured SMD at atomiser exit. My guide needs to present these results before a project review committee at Bangalore. Thus since last two days we are extracting the data from the result files stored at a particular interval. Data extraction is over just at five am this morning. Presently I am analysing the data.

Somebody has said, 'Research is all about patience and positive thinking without loosing the sight from the ground reality.'

Anyway why to say somebody has said that.. it's only me who just brought out that brilliant quote from my mind. Again... somebody has said that you are never to tell others that your quote is yours; saying 'somebody has said' makes it more impressive.

Interesting enough!!

First Gymkhana Meeting

Gymkhana Management Committe meeting was held at the Office of DoS. This committee overviews functioning of the all organisations instituted to take care of co-curricular and extra-curricular activities of students and also staff and their families. These activities include sports, cultural and hobby club events. This also governs technical festival Shaastra and cultural festival Saarang. Few noteworthy points disussed/informed were

• Installation of BOSE sound system in SAC this month
• Proposed partitioning and installing air conditioner in bowl area of SAC
• Introduction of Squash as a demo event in Sports Calender and proposal to build Squash Room
• Reorganising Hobby Club by encompassing discrete but well functioning groups like Scrabble Club, HAM Club (this dormant), Astronomy Club

DoS mentioned about the scoreboard that was build by our students. It is not functioning well at present. I need to look into what has gone wrong. Anyway I know the students who were involved in this work.

Dish TV installation differed due to unavailability of popular channels

In my visit to Annamalai Ent just some time back it is revealed that Dish TV does not provide ESPN, Start TV channels, Channel V and MTV. These channels being most viewed channels can not be kept away from consideration. Thus I have decided to differ installation of Dish TV in hostels. I have informed all concerned hostel secretaries, CCW and DoS about this. It is known that some other companies also are entering into this spree. We will consider those options as and when they are available.

Bhushan meets GS for message board and website

Bhushan and Arun met GS and disussed many points we decided. GS has approved the IPB message board. He has suggested me to write to new DP about individual webpages which I will do ASAP.

First BAR meeting of academic year

I requested RAS to meet fifteen minutes before Board of Academic Research (BAR) meeting in order to discuss about any issue to be raised. In this meeting nothing much was there for agenda with students participation. I anyway saught some clarification from DoAR about student exchange programs and MoU with other universities and research institutes.

• I was told that DAAD funds students completely making it an unique program.
• I talked about participation of MS and PhS scholars in such program as it is very mearge at present.
• DoAR said that some content from MoUs can be put up on the website and he will soon hand over the details to us. RAS has to collect from him.
• I was told that MS scholarship can not be revised as it is decided by MHRD.
• I was also told that PhD scholarship is continued for one year beyond stipulated four years but amount is only half of the regular scholarship. It was told that this decision has been taken two - three months back. But in my knowledge no any official announcement is made by Academic Office.

Anyway after we came out Arun said that he wanted to talk about new placement wing for research scholars. I tested him by asking some questions which he answered reasonably. Anyway it was a good idea which I too had conceived since long. For reasons best known to him he did not raise it in the meeting. I have asked him to make a write his proposal clearly on paper so that this idea can be discussed further. Hope he will do it soon.
