This study aims to investigate auto glass tempering project. Heat transfer characteristics of heated glass plates during their cooling with mutually placed circular air jets have been experimentally investigated. 4 mm thick glass samples were used in the experiments. Cooling process has been performed with 16 mutually placed nozzles of 8 mm in diameter and 80 mm in length in staggered arrangement. Nozzles were made of seamless aluminum pipes. Experiments have been conducted for dimensionless jet to plate distances (H/D) between 1 and 10, and S/D ratios which represents dimensionless distance between nozzle axis, for 2?S/D?10. Reynolds number has been fixed at 30000 for all experiments. According to the results the highest average Nusselt number (Num) has been achieved for S/D=2 and H/D=4 with a value 123.3 and the lowest average Nusselt number was obtained for S/D=10 and H/D=10 with a value 58.6.trinfo:eu-repo/semantics/closedAccessAuto glass temperingCooling timeImpingement air jetsNusselt numberExperimental investigation of cooling with multiple air jets on auto glass temperingOto camlarin temperlenmesinde çarpan hava jetleri ile sogutmanin deneysel incelenmesiArticle2-s2.0-848724132057834Q277527
