About gas flow and buildings

Hello ! I have a question to make, which really bothered me these days and i couldnt find a solution. I am currently studying the consequences of a gas flow ( methane, ethane in particular ) which is released from a hole ( in a pipe ) of a given diameter D , and from a given height H. The pressure of the gas is 50 Bara and the temperature of the pipe is 60 oC. My first problem is now, how can i decide about the shape that this gas release will take, its volume, its concentration ? In addition to that, if i have a large building in a quite short distance from the leak, and the gas cloud hits the building with high pressure ( and of course high velocity ) how can i decide what happens to the this cloud after that ? If the case is that it spreads out, what shapes will the "pieces" of the gas cloud take and how can i decide about their direction, volume,mass assuming that there is no wind ?
Thanks a lot in advance |
