Heat Transfer Enhancement of a Flat Plate Boundary Layer Distributed by a Square Cylinder: Particle Image Velocimetry and Temperature-Sensitive Paint Measurements and Proper Orthogonal Decomposition Analysis
The current empirical study was conducted to investigate the wall neighborhood impact on the two-dimensional flow structure and heat transfer enhancement behind a square cylinder. The low- velocity open-circle wind tunnel was used to carry out the study tests considering the cylinder diameter (D)-based Reynolds number (ReD) of 5130. The selected items to compare were different gap he...
متن کاملThermal Product of Fast Response Temperature Sensors for Transient Heat Transfer Applications with Numerically Determined Surface Heat Flux History
A dynamic calibration technique for evaluating the thermal product values of different scratched temperature sensors is presented. These sensors have renewable junction, fast response time and it can be used for transient heat transfer measurements in hypersonic vehicles. Two types of scratch were used, mainly abrasive papers with different grit sizes and scalpel blades with different thickness...
متن کاملAccuracy of Pressure Sensitive Paint
Uncertainty in pressure sensitive paint (PSP) measurement is investigated from a standpoint of system modeling. A functional relation between the imaging system output and luminescent emission from PSP is obtained based on studies of radiative energy transports in PSP and photodetector response to luminescence. This relation provides insights into physical origins of various elemental error sou...
متن کاملLow-temperature heat transfer in nanowires.
A new regime of low-temperature heat transfer in suspended nanowires is predicted. It takes place when (i) only "acoustic" phonon modes of the wire are thermally populated and (ii) phonons are subject to the effective elastic scattering. Qualitatively, the main peculiarities of heat transfer originate due to the appearance of the flexural modes with high density of states in the wire phonon spe...
متن کاملNumerical study of heat transfer in fluidized bed dryers by volume of fluid method
The purpose of this study is numerical modeling of temperature variation of phases in a two phase regime in fluidized bed dryers including particles belonging to Group D of geldart classification. The mass transfer between phases is not taken into consideration in this modeling which has been assumed in three- dimensional, unsteady, and two-phase regime.To verify the modeling we consider the do...
