Öğe The efficiency of Al2O3 water nanofluid on a flat plate solar collector(SETCOR publications, 2015) Budak Ziyadanoğulları, Neşe; Yıldız, Cengiz; Argunhan, Zeki; Tekalp, Selen; Yücel, Halit LutfiSolar collectors are particular kind of heat exchangers that transform solar radiation energy into internal energy of the transport medium. One of the most effective methods is replacing the working fluid (water, ethylene glycol, engine oil…) by developing a new class of fluids with a higher thermal conductivity for thermal systems. In the present work the effect of Al2O3-water, as working fluid, on the efficiency of a flat plate solar collector is investigated experimentally. The mass flow rate of nanofluid is 150 Lit/h. The volume fraction of the nanoparticles is 0.2 %, 0.4 % and 0.8 % respectively. The results reveal the impact and importance of each of these parameters. Experimental results reveal that utilizing the nanofluid increases the collector efficiency in comparison to water as an absorbing mediumÖğe The experimental study of nanofluids on a flat-plate solar collector(Fırat Üniversitesi, 2017) Budak Ziyadanoğulları, Neşe; Yücel, Halit Lutfi; Yıldız, Cengiz; Işık, Mehmet KemalSolar collectors are particular kind of heat exchangers that transform solar radiation energy into internal energy of the transport medium.

Biophotovoltaic (BPV) devices are biological solar cells that convert the energy released into electrical energy by microorganisms such as algae. A series of reactions occurs when the solar radiation falls on the alga. Water is divided into three parts: proton (H + ion), electron and oxygen. These ions and the element of oxygen are vital for the inorganic substances contained in carbohydrates and proteins, which allow the growth of alga. Electricity is produced when the sensor is placed in a system containing two electrodes separated by a membrane that allows only protons to pass through. Electrons produced during photosynthesis pass through an external circuit to water form and reunite with proton and oxygen at the reductive electrode (cathode). Electricity is generated as a result of flow passing through the external circuit and can be used to operate electronic devices.Öğe Effects of nanofluids on the efficiency of a flat plate solar collector(Fırat Üniversitesi, 2015) Budak Ziyadanoğulları, Neşe; Yıldız, Cengiz; Yücel, Halit Lutfi
