An Eulerian multiphase frost model based on heat transfer measurements
Saygın, Alper; Başol, Altuğ Melik; Arık, Mehmet (Elsevier, 2023-12-01)In this paper, a laminar numerical model is developed to predict frost formation over a horizontal cold flat surface. An Eulerian-Eulerian multiphase approach is followed to model humid air and ice phases separately. Frost ... -
An experimental investigation into frost accumulation over vertical finned and unfinned surfaces during impinging air flow
Öksüz, Enes Abdülhakim; Saygın, Alper; Başol, Altuğ Melik; Budaklı, M.; Arık, Mehmet (ASME, 2020)Frost formation on evaporators negatively affects the cooling performance of refrigerators. It increases the thermal resistance between the refrigerant and air leading to a reduction in the system cooling capacity. In this ... -
An experimental study on the frost formation over a flat plate: Effect of frosting on heat transfer
Saygın, Alper; Başol, Altuğ Melik; Arık, Mehmet (Elsevier, 2023-06-01)Frost accumulation on cooled surfaces generates thermal barrier between the surface and air. Apart from the frost layer thickness, the thermal properties of the frost also affect its heat transfer characteristics. In this ... -
Investigation of soot formation of ethylene/air jet diffusion flame with rank correlated slw including ethylene and acetylene radiation
Halvaşi, Berkay; Başol, Altuğ Melik; Mengüç, Mustafa Pınar; Ertunç, Özgür (Begell House Inc., 2023)Radiation is significant, especially in sooting flames.

Numerical analysis and diffuser vane shape optimization of a radial compressor with the open-source software su2
Uzuner, Mustafa Kürşat; Başol, Altuğ Melik; Mischo, B.; Jenny, P. (Turk Isi Bilimi ve Teknigi Dernegi, 2023)In recent years, the usage of open-source computational fluid dynamics tools is on a rise both in industry and academia. SU2 is one of these open-source tools. Unlike other open-source alternatives, SU2 is equipped with ... -
Numerical analysis of the radiant heating effectiveness of a continuous glass annealing furnace
Altun, Gönenç Can; Başol, Altuğ Melik (Elsevier, 2022-03-05)Radiative heat transfer is the dominant mode of heat transfer in glass annealing furnaces. Especially in electrically heated furnaces due to the nonparticipating nature of the furnace atmosphere the radiative heat transfer ... -
A numerical investigation into frost formation under impinging flow conditions
Saygın, Alper; Öksüz, Enes Abdülhakim; Başol, Altuğ Melik; Arık, Mehmet (IEEE, 2021)Frost formation is an undesired phenomenon for a wide range of practical applications as it diminishes amount of heat dissipation from heat transfer regions. In this paper, frost growth process on a vertically suspended ... -
On the individual droplet growth modeling and heat transfer analysis in dropwise condensation
Azarifar, Mohammad; Budaklı, M.; Başol, Altuğ Melik; Arık, Mehmet (IEEE, 2021-10)The low convective coefficient at condenser part of spreaders and vapor chambers due to film blanket blocking encourages utilizing dropwise condensation (DWC). Challenges exist in the experimental characterization of DWC, ... -
