Boiling Heat Transfer Simulation in Rectangular Mili-Channels
Koca, Aliihsan; Khalaji, Mansour Nasiri; Sepahyar, Soroush (Yıldız Teknik Üniversitesi, 2021)Due to the high heat transfer coefficient and compactness of a system, mili-channel-based cooling and heating techniques are greatly expected to be distributing high heat flux from the electronic devices. In terms of ... -
A Comprehensive Approach to Analyze the Discrepancies in Heat Transfer Characteristics Pertaining to Radiant Ceiling Heating System
Karakoyun, Yakup; Açıkgöz, Özgen; Çebi, Alican; Koca, Aliihsan; Çetin, Gürsel; Dalkılıç, Ahmet Selim; Wongwises, Somchai (Elsevier, 2021)Radiant heating/cooling systems are being popular thanks to their ability of regulating the living-environment with the use of low temperature heating and high temperature cooling. In this work, an artificial neural network ... -
