This Chapter summarises existing knowledge about near field of fluidjets impinging upon a solid wall. In particular, the chapter focuses attention on submerged jets (those having the same density as the surrounding more or less stationary outside fluid) in which the impingement is complicated by vortical structures formed due to hydrodynamic instability on the jet outer edge. Because the most important engineering application of such flows is in transfer of heat and mass into/from fluid to the wall, the chapter pays considerable attention not only to the fluid mechanics of the impingement flow but also to basic problems of the convective transfer. Particular space is also devoted to interesting cases of impinging jets issuing from annular nozzles, the flowfield of which exhibits some special features of importance for applications. The last part of the chapter discusses, due to their recently increasing importance, impinging jets excited so as to get a pulsating and hybrid-synthetic character.
