THERMAL BOUNDARY LAYER MEASUREMENTS USING A MULTIPLE THIN WIRE RESISTANCE THERMOMETER IN AN INTERNAL COMBUSTION ENGINE

DEPENDENT ABSORPTION AND SCATTERING BY INTERACTING NANOPARTICLES Donmezer, Fatma Nazli; MENGÜÇ, MUSTAFA PINAR; Okutucu Özyurt, Hanife Tuba (2010-01-01) Dependent light scattering and absorption patterns of metallic nano-sized particles in interaction with other spherical and cone-like structures were investigated. The numerical solution of the light scattering problem was obtained using DDSCAT7.0 code. The surface integration of the Poynting vector is performed to estimate the spectral absorption by individual particles. Parametric studies were conducted to examine the effects of different parameters, including the geometry, size, shape and the position of...
Energy analysis of a solar assisted absorption heat pump for floor heating system Sarı, Özgür Gökmen; Yamalı, Cemil; Department of Mechanical Engineering (2004) Solar assisted single-stage absorption heat pump (AHP) was used to supply energy to a floor-heating system by using the exergy methods. An existing duplex-house,in Ankara, with a heating load of 25.5 kW was analysed. Heating loads of the spaces in the building were calculated and a floor heating panel was modelled for each space leading to the capacity of the AHP before it was designed. Solar energy was delivered to the evaporator and high temperature heat input delivered to the genarator are met by auxilia...
Single-phase forced convection in microchannels - A state-of-the-art review Yener, Y; Kakac, S; Avelino, M; Okutucu Özyurt, Hanife Tuba (2004-07-30)
APPLICATION OF SPECTRAL ANALYSIS TECHNIQUES TO CAVITATION IN CENTRIFUGAL PUMPS ERALP, OC; ORUC, S (1993-11-05) An experimental investigation has been performed to study the inception of cavitation and the effect of entrained air on cavitation in a double suction centrifugal pump. Experiments have been organized to cover off-design flow rates and reduced suction pressures independently so that has been possible to study both the effect of flow rate and suction pressure. Air of known amounts has been entrained from the suction pipe to investigate its effect on the intensity of cavitation and the performance of the pu...
Laminar filmwise condensation of flowing vapor on a sphere Erol, Doğuş; Yamalı, Cemil; Department of Mechanical Engineering (2004) The objective of this study is to analyze theoretically the laminar film condensation of water vapor flowing on a sphere. For this purpose, the problem was handled by including all of the two-phase boundary layer parameters such as gravity, effect of vapor shear, inertia, energy convection and pressure gradient. For this full two-phase boundary layer system, the boundary layer equations, boundary conditions and the interfacial conditions were first analyzed, and then discretized. A computer program in Mathc...
