Turbulators in cooling passages of small turbine blades often have geometric constraints placed upon them due to casting limitations associated with small dimensions. Problems such as core die wear, cavity fill imperfections, and casting tolerance va

A parametric study was conducted to experimentally determine the effects slot exit geometries have on film effectiveness (ijy) for several injection angles (a = 0.0, 5.0, 8.5, 11.5, and 15.0 deg). Such slot geometries are typically used on the pressu

Liquid crystals are used in this experimental investigation to measure the heat transfer coefficient in a spanwise rotating channel with two opposite rib-roughened walls. The ribs (also called turbulence promoters or turbulators) are configured in a

The main objective of this experimental investigation was to measure the convective heat transfer coefficient of impingement for different target wall roughness geometries of an airfoil leading edge, for jet to wall spacings and exit flow schemes. Av

Squirrel monkeys display an interest in novel places, habituate to new situations, and spend most of their daily activity in the wild in large groups engaging in feeding behaviors over a broad area. Captivity limits these behaviors and consequently m

Leading edge cooling cavities in modern gas turbine blades play an important role in maintaining the leading edge temperature at levels consistent with airfoil design life. These cavities often have a complex cross-sectional shape to be compatible wi
