Performance analysis of grooved heat pipes using 3-D multi-channel thermal resistance network
Sezmen, Ramazan Aykut; Dursunkaya, Zafer; Çetin, Barbaros; Department of Mechanical Engineering (2021-9)
Heat pipes are phase change heat transfer devices that transfer high amounts of heat with low temperature differences compared to conventional cooling techniques due to their high thermal conductivity. Since heat pipes do not require any external power supply and not involve any moving parts, they are preferred for high reliability applications and in wide range of industrial applications from thermal management of electronics to space applications. Essentially, heat pipes use the advantage of occurring pha...
Performance analysis of a solar-assisted heat pump with an evacuated tubular collector for domestic heating
Caglar, Ahmet; Yamali, Cemil (2012-11-01)
Performance of a solar-assisted heat pump with an evacuated tubular collector has been analyzed both theoretically and experimentally. A domestic heating system has been designed, constructed and tested. The evacuated tubular solar collector has been used to achieve higher collector efficiencies. The effects of evaporation temperature on the heating capacity and performance of the system have been investigated. Evaporation temperature varies between 5.2 and 20.7 degrees C while storage tank temperature vari...

Performance evaluation and comparison of low voltage grid-tied three-phase AC/DC converter configurations with SI and SIC semiconductor switches
Öztoprak, Oğuzhan; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2019)
In this thesis, as compared to silicon IGBT (Si-IGBT) technology, the advantages of using higher efficiency and faster wide bandgap silicon carbide (SiC) semiconductor switches in low voltage three-phase grid-tied PWM DC/AC voltage source converters (VSCs) are investigated in terms of sizing, efficiency and economic considerations for MW-scale photovoltaic power plant applications. As the cost and energy efficiency of a VSC strongly affect the total system economics, this thesis proposes a design methodolog...
