    Piston thermal analysis

    Latelly I have seen that Filipi published an interesting dynamic model but I am not able to tell more in the moment, I am not in my office where I have their paper. Try with search engine I think it is not so wide area you can find it.

    HELP ME!

    When you modify the files in Developers studio environment before running the program you will be asked to rebuild modified files. What is the problem with your fortran files and you have to change them every time before the new run?

    Turbo/supercharged Volumetric Efficiency

    VE=2*(mass flow rate_AIR)/(intake density*displacement volume*engine speed) well this is I think corect equetion acording to Watson and Jonata... not sure about +mass flow rate_FUEL

    Turbo/supercharged Volumetric Efficiency

    working volume = displacemant volume well, I made literal translation from my (Serbian/Bosnian) languarge

    Turbo/supercharged Volumetric Efficiency

    VE = RealMaassFlow / TheoreticalMassFlow Theoretical mass flow is working volume multiplyed with averaged density in intake manifold (or infront of intake valve) That is how formula for VE should be derived

    Turbo/supercharged Volumetric Efficiency

    VE = RealMassFlow / (VolumeCyl * AverageDensityInfrontOfValve)

    Turbo/supercharged Volumetric Efficiency

    Well, I do not know, I have seen 1,1 VE numers regulary... nothing unusual but max VE I dont know exactly... most of the books sey more then 1. P.S. Privat message to autor, I am making that spredsheet what I promist you for input data for my program... in the moment I am taking vacation 7 days...

    Turbine and Compressor maps, where to find it?

    http://www.majesticturbo.com/compression.html OK if comebody has similar problem... I still did not find Holset performance maps.

    Turbine and Compressor maps, where to find it?

    WOW people, I should buy you beer for this links!!! Great!

    Turbine and Compressor maps, where to find it?

    Thanks! I did not know that situation is so bad! If somebody hase in the catalogue "Holset H2D93 5 1 N/S28.B11" turbokompressor maps please scan it and send it on my mail zoransa@yahoo.com I will buy you a beer.

    Turbine and Compressor maps, where to find it?

    Is there any online resource or database of turbines and compressor maps. Especialy I am interested in KKK and HOLSET manufectors.

    Online Education - Any Good Engineering Programs?

    Just an idea, try to look at http://dmoz.org dictionary and find appropriate category. Humans do better then machines. Just a taught... I don't know any distant learning programs.

    Modelling and calculation of the chimney?

    thanks interesting site and software I am going to try it.

    Condensation in pipe lines-pneumatic conveying system

    I would try to solve diferential equotin and find out temperature profile along the pipeline and there I would find the point where condensation ocures... the problem is how to determine local coeficient of heat exchange bitween the pipe and ambient air.

    Kinetic subroutine for Aspen plus

    We could help ypu to write it but I do not know for an existing subroutine for copy-paste.

    Modelling and calculation of the chimney?

    Have you seen something from that field lately? Every reference is more then wellcome...

    Where could I find data about testing turbocharged dieselengine?

    I have made a mathematical model and I need experimental data to validate it. I need - basic engine geometry. - turbocharher maps or references where to find it. - intake exaust pipe geometry for 1-d simulation. - Preasure-time (or crankshaft angle) in the cilinder, intake and exaust pipe(s)...
