Parametrıc study of energy, exergy and thermoeconomıc analyses on a vapor-compressıon system cascaded wıth lıbr/water and nh3/water absorptıon cascade refrıgeratıon cycles

Dalkılıç, Ahmet Selim; Çelen, Ali; Çebi, Alican; Taner, Tolga; Wongwıses, Somchai (Anadolu Üniversitesi, 2017)

Energy savings on cooling systems can be achieved using novel refrigeration cycles. To this end, vapor-compression/vaporabsorption cascade refrigeration systems may be a substitute for single-stage vapor-compression ...
A review of flow boiling in mini and microchannel for enhanced geometries

Çebi, Alican; Çelen, Ali; Dönmez, Aydın Hacı; Karakoyun, Yakup; Celen, Pınar; Cellek, Mehmet Salih; Dalkılıç, Ahmet Selim; Taner, Tolga; Wongwises, Somchai (Yildiz Technical University, 2018)

Flow boiling researches in enhanced geometries practiced recently have been summarized in this review. Classical approximations in macroscale flows have not applied to the flows with small hydraulic diameters, so, this ...
Thermophysical and rheological properties of unitary and hybrid nanofluids

Mercan, Hatice; Çelen, Ali; Taner, Tolga (Elsevier, 2022)

Understanding the thermophysical properties of the working fluids in a heat transfer system is essential for improving the thermal performance of heat transfer equipment. Clarification of the complicated and entangled ...
