The paper presents a methodology for preliminary comparative assessment of the mixer (mixing device) efficiency. It is based on numerical simulation of mixing the two gases (with identical thermal properties) in a flow path with a mixer installed. Mixer efficiency is assessed by two criteria: mixing quality ѱ and relative total pressure loss The paper considers three types of mixers with the variable geometric dimensions to demonstrate the methodology. It shows simplicity of applying the mixer comparative assessment methodology, and identifies also its drawback, i.e. dependence of the results on the method of partitioning the inlet boundary for a separate gas supply.
