Abstract: This paper presents the results of the numerical investigation carried out on different tube designs to assess the impacts of variation in the geometry of the twisted tape on heat transfer, friction factor and thermal performance of water inside the tubes. Alternate-axis triangular cut twisted tape was considered and its pitch and width, as well as the perimeter of the cuts on it were varied. The walls of the tubes were subjected to a uniform heat flux condition. The results of the investigation reveal that the thermal performance of the tube designs improves with an increase in the width of the tape and an increase in the size of the cuts on the tape but diminishes as the pitch of the tape increases

ASSESSMENT OF THE EXISTING PREFABRICATED RC RESIDENTIAL BUILDINGS IN BULGARIA AND RECOMMENDATIONS FOR THEIR REHABILITATION AND STRENGTHENING
Published In: 2ND INTERNATIONAL CONFERENCE ON ADVANCES IN CIVIL, STRUCTURAL AND MECHANICAL ENGINEERING
Author(s): RANGELOVA FANTINA
Abstract: In this paper the different categories of prefabricated building systems for residential buildings in Bulgaria are first discussed. The most important problems of the “large-panel system” for residential buildings are commented. Contemporary techniques for rehabilitation and strengthening are presented. Finally, a few general conclusions and recommendations are given
