An analysis has been made to give a qualitative picture of the effects of wing sweep on the upwash at the propeller planes of multiengine airplanes. The method used in this analysis is, in general, the same as that given in NACA TN 2528, 1951, with the necessary extensions as suggested ...

This study investigates the effect of wing three-dimensionality on the structure of the wake-flow. This is accomplished here, by quantitatively describing the spatio-temporal variations in the velocity, vorticity and Reynolds stresses for the finite-span-wing case. Preliminary flow visualizations ...

In this study, water flow simulations around the propeller blades were performed using ANSYS Fluent code (ANSYS Inc., Canonsburg, PA, USA) to investigate the effect of a rope cutter installed on the ship’s propeller shaft on the water flow behind the propeller. The simulation results were va...
The effect of the Reynolds number on the flying wing common research model with a large sweep angle and small aspect ratio is studied by numerical simulation. The helicity cross-flow transition correction of the Langtry–Menter model is established in view of the deficient prediction accuracies ...
To demonstrate a batch sweep in action, we will use an example found in the Application Library of the COMSOL Multiphysics®core product: theElectric Sensor. This example model shows how to return an image of the interior of a box by applying a potential difference on the boundaries of the...
A Mettler Toledo differential scanning calorimeter (DSC) (Mettler Toledo, Mississauga, ON, Canada) was used to determine the glass transition temperature (Tg) of zein. The effect of water plasticization, or decrease in Tg, with increasing water activity (aw) was observed by equilibrating powdered...
The design and testing of Natural Laminar Flow (NLF) airfoils is examined. The NLF airfoil was designed for low speed, having a low profile drag at high chord Reynolds numbers. The success of the low speed NLF airfoil sparked interest in a high speed NLF airfoil applied to a single engine...
