... flow and presents the effects of varying sidewall gaps on heat transfer characteristics and friction factor in the open matrixes having rib angle 45 deg for three different subchannel aspect ratios 1.2, 0.8, and 0.4. Liquid crystal thermography has been utilized to discern the detailed heat transfer...

.... Local temperatures on the heated wall are measured by liquid crystal thermography. Distributions of the Nusselt number are obtained at different forced flow rates, applied heat flows, and transiting electrical currents. In correspondence of the point emitters, higher Nusselt numbers in the impingement...

... crystal thermography Increasing the efficiency and output of modern gas turbines is an incremental process. A critical area of focus for increasing overall efficiency is managing the amount of coolant used. Excessive use of coolant air decreases both thermal efficiency and output of the engine...

...Lei Wang; Bengt Sundén; Andreas Borg; Hans Abrahamsson The heat transfer characteristics of an impinging jet into a crossflow have been investigated by the liquid crystal thermography technique. The jet nozzle is circular and is inclined at 10 deg with respect to the target wall. In a turbulent...

... and they scale on the thickness of the fluid layer. This investigation documents the formation of cells in the liquid film in the presence of a uniform-heat-flux lower boundary condition. Liquid crystal thermography was used to image the cells and measure the temperature distribution on the lower surface...

... of convective heat transfer coefficients on the endwall within the wakes using Liquid Crystal Thermography, total pressure loss surveys by Kiel probe traverses and two-dimensional Particle Image Velocimetry (PIV) measurements within the wakes at the midplane of the test section. Measurements are performed...
