• Boundary layer flow
• Velocity profile
• Temperature profile
• Truncation

The concept of boundary layer flow, introduced in 1904 by Prandtl, is a popular field in Fluid Mechanics for engineers, physicists and mathematicians. The present work is a critique to many papers published in the last 15 years in the field of boundary layer flow. The critique concerns the shape of velocity, temperature and concentration profiles which are truncated due to small calculation domain used during the numerical solution procedure. These truncated profiles are not compatible with the boundary layer theory and introduce errors in wall shear stress and wall heat transfer values.
