AN APPROACH TO OBTAIN THE HEAT TRANSFER COEFFICIENT OF AQUEOUS SUCROSE SOLUTIONS IN AGITATED BOILING VESSELS

Özdemir, Mehmet; Durmaz, Ufuk (VINCA INST NUCLEAR SCI, 2015)

In this study, the heat transfer mechanism under agitated pool boiling was examined experimentally. Aqueous sugar solutions were used in a centrically agitated vessel. The effects of the gap which is between the impeller ...
AN EXPERIMENTAL INVESTIGATION OF SOLID OXIDE FUEL CELL PERFORMANCE AT VARIABLE OPERATING CONDITIONS

Taymaz, İmdat (VINCA INST NUCLEAR SCI, 2016)

Cell temperature and selection of the reactant gases are crucial parameters for the design and optimization of fuel cell performance. In this study, effect of operating conditions on the performance of solid oxide fuel ...
CHARACTERISTICS OF HEAT TRANSFER AND PRESSURE DROP IN A CHEVRON-TYPE PLATE HEAT EXCHANGER WITH Al2O3-WATER NANOFLUIDS

Ünverdi, Murat; Yasar Islamoglu (VINCA INST NUCLEAR SCI, 2017)

In this study, heat transfer and pressure drop characteristics have been experimentally investigated by using Al2O3-water nanofluids in the chevron-type plate heat exchanger. The purpose of the experiments was to determine ...
Experimental and Theoretical Analysis of Heat Transfer Characteristics in a Rectangular Duct with Jet Impingement

Uysal, Ünal; Şahin, Fatih (BEGELL HOUSE INC, 2010)

The heat transfer characteristics are analyzed in a rectangular cross section duct where impingement jet technique is applied for the purpose of heating and cooling. Heat transfer characteristics on surfaces are calculated ...
EXPERIMENTAL VALIDATION OF LMTD METHOD FOR MICROSCALE HEAT TRANSFER

Parlak, Nezaket; Gür, Mesut; Engin, Tahsin; Küçük, Hasan (YILDIZ TECHNICAL UNIV, 2017)

The single phase fluid flow and heat transfer characteristic has been investigated experimentally. Experiments were conducted to cover transition zone for the Reynolds numbers ranging from 100 to 4800 by fused silica and ...
NUMERICAL INVESTIGATION OF INCOMPRESSIBLE FLUID FLOW AND HEAT TRANSFER ACROSS A BLUFF BODY IN A CHANNEL FLOW

Taymaz, İmdat; Erman Aslav; Ali Cemal Benim (VINCA INST NUCLEAR SCI, 2015)

The lattice Boltzmann method is applied to computationally investigate the laminar flow and heat transfer of an incompressible fluid with constant material properties in a 2-D channel with a built-in bluff body. In this ...
PERFORMANCE AND EMISSIONS OF AN ENGINE FUELLED WITH A BIODIESEL FUEL PRODUCED FROM ANIMAL FATS

Taymaz, İmdat; Çoban, Mehmet (VINCA INST NUCLEAR SCI, 2013)

Oil reserves which are located around the world are declining day by day, so new alternative energy sources must be invented for engines of internal combustion and compression ignition, so biodiesel that is an alternative ...
