ABSTRACT
The standard tools of investigation involve both theoretical and physical experimentation. This chapter introduces some important aspects of physical experimentation that would be useful in any Coanda effect investigation. It considers the conservation equations mainly in their final form and highlight the rationale that can be used to simplify them further for different scenarios. The chapter aims to understand the flow physics better and interpret more effectively the results obtained utilizing these equations. Most flows of practical significance are turbulent. Except for simple cases, turbulent flows have always proved extremely difficult, if not impossible, to solve. Coanda flows occurring on walls with curvature are significant and complex. P. Bradshaw has provided a comprehensive review of the longitudinal streamline curvature on turbulent flow. The limitation of the Pitot-static probe is that it is one-dimensional, i.e., capable of measuring one component of the velocity or when aligned to the direction of the flow.
