Steady-state heat transfer from rectangular fin arrays is examined experimentally and numerically for turbulent fully developed flow. The effects of geometrical parameters on heat transfer coefficient and Nusselt number are investigated. For different inter fin ratios, Reynolds number and Nusselt number dependence of the results is investigated. A generalized empirical correlation for Nusselt number is developed for rectangular fins for a Reynolds number range of 17 x 10(7) < Re < 2.47 x 10(8), and an aspect ratio of 0.089 < d/w < 0.0625, 0.24875 < t/L < 0.729. The correlation can predict the results with a relative rms error of 11.14%. (C) 2016 Elsevier Masson SAS. All rights reserved.

EXPERIMENTAL AND NUMERICAL STUDY ON HEAT TRANSFER PERFORMANCE OF SQUARE, CYLINDRICAL AND PLATE HEAT SINKS IN EXTERNAL TRANSITION FLOW REGIME İnci, Aykut Barış; Bayer, Özgür (2019-01-01) Geometrical optimization of heat sinks with square, cylindrical and plate fins for heat transfer increase is numerically analyzed in transition regime external flow. The relations between the thermal characteristics of fins and boundary conditions such as free-stream velocity are investigated. Experimental studies are performed by using manufacturable fins to validate the numerical model. Heat transfer correlations are derived in order to determine average heat transfer coefficients over a certain range of ...
Numerical and experimental analysis for comparison of square, cylindrical and plate fin arrays in external flow İnci, Aykut Barış; Bayer, Özgür; Department of Mechanical Engineering (2018) Geometrical optimization of square, cylindrical and plate fins for heat transfer augmentation is numerically performed in the external flow. Heat transfer performance of fins with different profiles are compared with same Reynolds number. The relation between the thermal characteristic of fins and boundary conditions like free-stream velocity and heat input are investigated. Experimental studies are performed using manufacturable fins to validate numerical model. Heat transfer correlations are derived in or...
Numerical Simulation of Reciprocating Flow Forced Convection in Two-Dimensional Channels Sert, Cüneyt (ASME International, 2003-5-20) <jats:p>Numerical simulations of laminar, forced convection heat transfer for reciprocating, two-dimensional channel flows are performed as a function of the penetration length, Womersley (α) and Prandtl (Pr) numbers. The numerical algorithm is based on a spectral element formulation, which enables high-order spatial resolution with exponential decay of discretization errors, and second-order time-accuracy. Uniform heat flux and constant temperature boundary conditions are imposed on certain regions of the ...
Numerical simulation of thermal convection under the influence of a magnetic field by using solenoidal bases Yarımpabuç, Durmuş; Tarman, Işık Hakan; Department of Engineering Sciences (2011) The effect of an imposed magnetic field on the thermal convection between rigid plates heated from below under the influence of gravity is numerically simulated in a computational domain with periodic horizontal extent. The numerical technique is based on solenoidal basis functions satisfying the boundary conditions for both velocity and induced magnetic field. The expansion bases for the thermal field are also constructed to satisfy the boundary conditions. The governing partial differential equations are ...
Experimental investigation of single phase liquid flow and heat transfer in multiport minichannels Altınöz, Mesru; Güvenç Yazıcıoğlu, Almıla; Baker, Derek Keıth; Department of Mechanical Engineering (2013) This thesis aims to experimentally investigate pressure drop and heat transfer characteristics of single phase water flow in rectangular minichannels. The small channels are an area of interest in heat transfer field since 1970’s owing to their enhanced heat transfer characteristics. However, the heat transfer and pressure drop characteristics of these channels are not fully established as there is a wide number of studies in literature showing inconsistent results with each other. In order to investigate t...
