Please Review My two-paragraph text (I wrote it as part of scientific paper))

Flow around bluff bodies and its resulted vortex shedding phenomenon is very important because of scientific aspects in engineering. One of the aspects of research on the flow around the cylinders that has been less investigated is sound production. Cylinders can have a significant impact on daily life. Such examples are including sound propagation from buildings, aircraft landing equipment, and wheels system, pantograph of trains and wind mirrors.

Most of the researches that have been carried out in this field have addressed the prediction and reduction of noise produced by a circular cylinder [1]. There are several researches on the oscillating forces resulted from vortex shedding of the square cylinder [2][3][4]. Muller [5], by using Large Eddy Simulation (LES) turbulence model investigated the flow pattern around the square cylinder in three attack angles of 0, 13 and 45. Based on his results, in critical attack angle of 13°, the flow pattern is changed. In this attack angle, flow separation and reattachment to the surface are happened at the front edge and near the rear edge, respectively.
