Numerical investigation of heat transfer using impinging jets on triangular and square ribbed roughened walls
Çalışır, Tamer; Çalışkan, Sinan; Kılıç, Mustafa; Başkaya, Şenol (Turkish Society for Thermal Science and Technology, 2017)This paper presents a heat removal study on triangular and square ribbed surfaces under an array of impinging air jets. The investigation was carried out using nozzles with a 7x3 rectangular array of circular jets. The ... -
Second law analysis and heat transfer in a cross-flow heat exchanger with a new winglet-type vortex generator
Kotcioğlu, İsak; Çalışkan, Sinan; Cansız, Ahmet; Başkaya, Şenol (Elsevier Ltd, 2010)In this paper a second law analysis of a cross-flow heat exchanger (HX) is studied in the presence of a balance between the entropy generation due to heat transfer and fluid friction. The entropy generation in a cross-flow ... -
Sizing problem for a cross flow heat exchanger with wing-type vortex generator
In the present study, sizing of a single pass cross flow heat exchanger with unmixed fluid streams has been investigated. The heat exchanger is a cross flow heat exchanger. It has overall dimensions of 20 × 20 × 20 cm. Two ... -
Transient turbulent flow and heat transfer phenomena in plate-fin type cross-flow heat exchanger
In this article, a transient performance of a plate-fin cross-flow heat exchanger with convergent-divergent longitudinal vortex generators is investigated. The effect of flow geometry is taken into account to analyze the ... -
