Went in today to attend a seminar given by my supervisor, who is also head of the school. Not surprisingly, it was the biggest turnout of audience to these weekly seminars that I have seen LOL. It was actually not as bad as I thought it would be, lacking the equations that I was dreading and I didn't fall asleep in it. I nearly did towards the end when it was getting beyond my knowledge and abilities to understand, but he concluded. The questions that he got about the work were interesting because I could semi answer some of them, and even fully answer a few too, so I think my broad understanding of the work was probably greater than I originally thought.
It was mainly examining multi-scale approaches of modelling the gas flow patterns within spray dryers for determination of particle wall deposits, and usage of computational fluid dynamics (CFD) to model this. It was interesting to see that the newer approaches of CFD were very different in the results and answers compared to those of old. It would be expected that they would be better, but the drastic change.... very surprising. The old methods of static flow patterns now seem obsolete compared to transient flow patterns for spray drying. It was also interesting to learn that this work has been applied to other fields like combustion....
Post seminar, I went across to the EMU and took the other resin samples out of the curing oven and popped them from their containers, and then flipped them upsidedown and back into the oven to cure some more with more exposed surfaces. I will be probably going to start polishing next week to expose the clay surfaces, and to cut them to suit EDS viewing.
Oh, I had a chat with one of the students in my group, about this paper he had read. It was about spray drying but they didn't call it spray drying. Essentially, they were using liquid CO2 and dissolving it into the solvent. Then heating it to supercritical point, and spraying the liquid into a chamber. The pressure and temperature changes cause the CO2 to turn into gaseous state and forms a ultrafine mist of the solution, while because it is heated, the ultrafine mist evaporates off the solvent.... They don't have a aspirator flow like in normal spray dryers, but it really is spray drying by definition, they are just combining the heat and atomisation steps into a different form.... They just don't want to be associated with us proper engineers haha.
Well, been playing DDO a bit now with my monk, Emptyhanded, he's level 5.3 at the moment, and starting on Tangleroot adventure area for xp grinding. There has been a sudden influx of 'Chinese' players on Sarlona lately, and I couldn't really understand why it had happened since they were never around before, and also because I had known there were asian servers to cater for them. You can tell that it's Chinese players because in the LFM's they say zhonguolen only or Chinese, and the toon names are like Xiaoling or Baozi or other 'ping-ying' names.... I got into a party with one, and they didn't use voice chat but their party chat was all in ping-ying, and I could follow along if I read it out aloud LOL. I was thinking, were they plat farmers? I got an answer from one of these guys in the party, apparently the DDO China servers got taken down. Permanently? I don't know, so they have all flooded over to the US servers. Perhaps this is a sign of the apocolypse, with not enough population to keep the asian servers, they got turned off and more people crammed into the US servers.... doom and gloom perhaps for DDO? Mod 7 with the introduction of Monks didn't really seem to pick up too much interest for the community, since their competitor, Age of Conan, even with all of the bugs and contraversy regarding pre-ordered blah and blah, is drawing more and more players away.... even my friends play it now instead of DDO and are trying to get me onto it instead..... But, I like DDO, and I have spent my time and effort with my characters, so I'll presevere for a while to come, and I've paid my subscription anyway haha.
