    Author(s): Mushfiq Al Arafa*, Macdonald Mutekwa and Zhaolin Chen

    The numerical parametric analysis conducted to analyze the impact of Micro-Blowing Technique (MBT) wholeparameters is quite few at the present stage. The main aim of this research paper is to analyze the effect of micro blowing flow rate and its different hole-parameters on the skin friction drag reduction of an aircraft engine nacelle operating at cruise conditions. The primary tasks are focused to understand the behavior of the flow characteristics at the vicinity of the micro-porous holes by means of different types of MBT configurations. The interaction between main-stream flow and the micro-channel flow is numerically solved by using the Reynolds average Navier-Stokes equation and the k-omega SST is used to model the turbulent flow at the vicinity of the wall region. The hole-pattern is kept aligned in a single-row channel and the shape of the whole cross-section is kept straigh.. Read More»
