This chapter investigates the wakeWake dynamics formed downstream of a blunt bodyBlunt body under various motionMotion states. The wakeWake evolution of the blunt bodies is analyzed. The typical blunt bodies include cylindersCylinder, spheresSphere, and prismsPrism. The motionMotion of the blunt bodyBlunt body is defined as its relative motionMotion with the flow field. Thus, the static blunt bodies in uniform flow fields are classified as translational motion.
