In this study, the critical heat flux (CHF) in subcooled flow of Freon-113 through short vertical tubes has been investigated. In addition, the concept of local tangential flow injection has been studied as a means of CHF enhancement. The data without tangential injection (axial flow) indicate that there is an effect of heated length in the limit of very short tubes. The CHF data obtained with tangential injection show as much as 67% enhancement in CHF over axial flow data at the same conditions. In addition, it has been shown that local tangential injection could be utilized in non-uniform heating situations.
