Viability of Cross-Flow Fan for Vertical Take-Off and Landing Aircraft
… design that, when paired with an off-the-shelf cross-flow fan rotor, will generate a trust-to-weight ratio significant enough to allow for vertical take-off. The commercial computational fluid dynamics software, ANSYS CFX, was used to perform a computational analysis of various housing designs …

Feasibility Study of a Multi-Purpose Aircraft Concept with a Leading-Edge Cross-Flow Fan
<p>A wing-embedded Cross-Flow Fan (CFF) was first proposed as an active flow control (AFC) device nearly 40 years ago. The CFF can be employed as a propulsion device as well as a high-lift system. This thesis research focuses on investigating the use of CFF as a high-lift device for an Extremely …

Parametric Study of Aerodynamic Performance of an Airfoil with Active Circulation Control Using Leading Edge Embedded Cross-Flow Fan
<p>A concept of a cross-flow fan (CFF) embedded near the leading edge of an airfoil to actively control the boundary layer for lift and thrust enhancement has been proposed. The design places a cross-flow fan near the leading edge of an airfoil and flow is drawn in from the pressure side of the …

Experimental evaluation of a propulsive wing concept
… Mach number of 0.7 for extended runs of laminar flow, pressure thrust, and wake filling. A lowspeed wind tunnel test was performed using a model of the designed propulsive airfoil section in order to validate the tools which were used for design, as well as to verify the pressure thrust concept. …

Mixed convection and heat management in the Mars gravity biosatellite
… rejection from the payload to the bus module via fan/heatsink/thermoelectric cooler units. Circulation effectiveness is measured by the Richardson number, which expresses the ratio of the influence of free convection to the influence of forced convection in a mixed-convection flow. Experiments …

A Volume-Force Synthetic Disturbance Approach for High-Fidelity of Unsteady Fluid Structure Interactions
… to be applicable to boundary layer type of flows. Then, selected applications of the momentum source model are considered including: gust-airfoil unsteady interactions, turbulence-airfoil unsteady interactions, Analysis of the turbulence effect on acoustic radiation of a novel airfoil design …
