The paper considers and compares simplified approaches to a problem of determining the gas flow parameters in a curved channel with the constant cross-section. Gas parameters are computed for six channels with the different radii and rotation angles within the framework of each approach. The obtained results are compared with the reference computation data received using the computational gas dynamics. Applicability of the most adequate approach to assessing the gas flow parameters in the narrowing curved channel is checked. The paper provides conclusions on applicability of each of the considered approaches.
