Performa Termal dan Hidrolik Aliran Udara Melalui Vortex Generator Berlubang Tipe Concave Rectangular Winglet di dalam Saluran Persegiempat: Studi Eksperimen
Autor: Syaiful Syaiful, Ahmadi Syarif, Bambang Yunianto, Nazaruddin Sinaga
Publikováno v: Rekayasa Mesin, Vol 11, Iss 2, Pp 233-245 (2020)
Fin and tube heat exchangers use gas as a cooling/heating medium on the fin side. The low thermal conductivity of gases results in high thermal resistance, which results in a low rate of heat transfer. Therefore, the researchers sought to reduce ther

Effect of Attack Angle of Concave and Convex Winglets Vortex Generators on Thermal-Hydraulic Performance of Fin and Tube Heat Exchangers with Field Synergy Principle
Autor: T K Berkah Fajar, Carisya Dara Salsabila, Bambang Yunianto, Maria F. Soetanto, Syaiful
Publikováno v: International Journal of Heat and Technology. 39:797-809
In fin and tube heat exchangers, the gas passing through the fin has a lower thermal conductivity than the fluid passing through the tube. The low thermal conductivity brings a high thermal resistance, which suppresses the heat transfer rate. A commo
