duoxiangliu.zip - Due to low compressibility factor of CO2 near the critical point and inside the supercritical dome, ideal gas assumption decreases the accuracy of the result significantly. plz tell more information and what have you done to prevent divergence? (time step, discritization, look-up table range and size, initial solution, boundary conditions, ...),2020-05-25 18:22:05,下载0次
duoxiangliu.zip - You can generate the properties of any fluid through REFPROP like viscosity, density, thermal conductivity etc. But this software is not available online. I am simulating the same problem by using supercritical water but i am facing convergence issues. If you guyz know about this. My channel is 2*2 rod bundle with constant heat flux and water at 25MPa,2020-05-25 18:19:46,下载1次
cfx.zip - I am trying to simulate a Natural Circulation Loop.I have to specify the properties of co2 like specific heat,density etc. but since the temperature is varying throughout the loop, I have to specify the properties at different temperatures. But instead of doing that can the software REFPROP be connected to FLUENT so that it automatically picks up the values?
Any help will do.Thnx,2020-05-25 18:17:27,下载1次
cfd.zip - You use refprop to generate a table and then CFX uses the table during the computation. I would contact ANSYS support and they can set you up with the refprop table generator.,2020-05-25 18:15:12,下载1次
test.zip - in CFX-Post i use probe to find one point state
then i key the pressure and temperature to find density (RefProp)
i try to create a new material
and follow the process as you say
but the CFX-Pre warring that i need Thermal Conductivity and Viscosity
then i turn on Transpot Properties (Viscosity and Conductivity)
and use the same as real gas combustion>CO2 set
i also set max./min. temp. and pressure to simulate work condition
but the result still wrong
i have searched on internet for days
i found some method that import a excel data or RGP file to create new material
but i don't how to do it or create RGP file,2020-05-25 18:10:38,下载1次
