Cavity-backed T-fed slot antenna
Cavity-backed slot antennas are experiencing a revival because of the ever-increasing need for low-profile and conformal antennas which have a low radar cross section out of their operating frequency bands. Like thin microstrip patch antennas, cavity-backed slot antennas typically have a narrow …

Effects of Surface Conditions on Endwall Film-Cooling
… A typical endwall design includes a leakage slot at the interface between the combustor and the vane, a leakage slot at the vane-to-vane interface and film-cooling holes. In addition, with the increase in energy demands and depletion of natural gas resources, alternate fuels such as coal …

Impact of Design Parameters on Detached-Die Tapered Resin Injection Pultrusion
… parameters (the length of the injection chamber, slot width, multiple injection slot locations, and part thickness) on the performances and complete wetout of the composite parts for both the attached-die and detached-die configurations is investigated with various chamber lengths and compression …

Parametric Investigation of the Combustor-Turbine Interface Leakage Geometry
… part life. Bypass leakage flow emerging from the slot between the combustor and turbine endwalls can be utilized for cooling purposes if properly designed. This study examines a three-dimensional slot geometry, scalloped to manipulated leakage flow distribution. Statistical techniques are used to …

High lift configuration of a slotted natural laminar flow airfoil
Experiments were performed on a slotted natural laminar flow airfoil, the S414. The slotted natural laminar flow airfoil concept was developed to satisfy design constraints of high maximum lift and low profile drag. A two-element natural laminar flow configuration allows the typical rapid …

Use of the hole pressure data to obtain N1 at high shear rates for polymer melts
A slit die with a rectangular slot placed transverse to the flow direction has been used for both flow visualization and direct pressure measurements of the hole pressure (Ph). The results from these measurements have been used to evaluate the Higashitani-Pritchard-Baird (HPB) equation which has …
