摘要: Abstract A simple technique is suggested for constructing approximate relations with wide ranges of applicability (the same formula can be employed to describe a variety qualitatively identical problems which differ geometrically, i.e. in the surface shape, flow pattern, etc.). The based on transition from ordinary dimensionless variables special asymptotic coordinates. illustration made by reference numerous specific theories mass and heat transfer physicochemical hydrodynamics. Comparison obtained number typical cases, exact, numerical, results are already available, shows good accuracy great capabilities method. method also used success other fields chemical engineering science, mechanics physics.
