An engineering firm was awarded a project for realizing a redesign of a gas turbine bypass stack. Important specifications for such a stack are minimal flow resistance and reduction of noise levels. For optimal functioning of the gas turbine, low downstream pressure drop is important (backpressure), sound levels need to meet legal requirements
The client has realized a basic design for meeting these demands, and Mateq Process was requested to analyze the design for flow pattern and pressure drop. Also the connection of the stack to an existing communal stack tip was analyzed, any recirculation patterns there can be a cause of noise and additional pressure drop.
