Abstract: First part of a survey drawing together findings of authors' research over a period of two decades on enhancing performance of impinging jets. The limiting factor is stagnant near-wall layer across which the transfer takes place by conduction. Results of research aimed at removing this limitation have been partly published but mostly in literature inaccessible to international readers. Flow visualizations played an important role in identifying the problem areas, leading to a number of novel implementation concepts to be described in the second part.
