Nowadays, the research interest in the modeling near wall region in turbomachinery flows is directed towards boundary layers which are not fully turbulent but laminar and transitional, especially under the condition of wake unsteadiness. The paper presents the review of recent achievements in interpretation of by-pass and wake induced transition processes and the most important aspects of transition modeling. This review is complemented by physical explanation of those phenomena based on the latest literature data as well as on the results of numerical and experimental investigations performed at the Institute of Thermal Machinery.
