Hi all,<\/p>\n

Just a quick question regarding the fluid domain of a CFX simulation. My set up has an axial gas turbine blade with a larger box-like fluid domain. I am only interested in analysing the heat transfer from the hot fluid domain to the blade. The boundary conditions are an inlet velocity and an outlet static pressure, with symmetry conditions for the fluid at the blade hub and tip, as well as free slip walls that run parallel to the flow direction.<\/p>\n

My problem is that i am not sure if the fluid domain should be stationary or rotational, and i have had no luck searching online for when a rotation domain is required. Additionally, I have no other blades or domains besides the single blade\/gas domain for the analysis. Any advice on this would be greatly appreciated.<\/p>\n

Thanks !<\/p>\n","protected":false},"template":"","class_list":["post-167676","topic","type-topic","status-closed","hentry","topic-tag-fluid-domain-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
