19.1 Introduction

Thermal resistance in heat exchange systems is being reduced as much as feasible. As a passive heat transfer enhancement strategy, swirl flow generators can be incorporated into the base flow [1]. As a result, they form three-dimensional longitudinal vortices that promote bulk mixing in the ...
