RÉSUMÉ

The paper presents the assessment of the efficiency of the augmentation method which consists in simultaneous use of twisted and transit flows moving along the gap formed by concave and convex surfaces of the annulus and along the convex heat transfer surface, respectively. It has been shown that, as compared to a smooth channel or a twisted flow channel, the simultaneous use of twisted and transit flows allows heat removal rate and critical heat flux to be significantly increased on both heat transfer surfaces.
