Grinding Cocoa Changes Chocolate Properties, Joseph Cooney

Research on Capitol Hill

This research studies how the viscoelastic properties of chocolate change through the 72-hour grinding process of chocolate manufacturing. Utah State University's Aggie Chocolate Factory produces chocolate from single-origin sources, each of which has a unique flavor, and thus a unique chemistry. This research explores the effects of grinding time on the viscoelasticity of each of these origins' chocolate types, including dark, sweet dark chocolate, and milk chocolate. Chocolate is a non-Newtonian fluid and therefore the Casson model (eq. 1) was used to obtain values for viscosity and yield stress, τ^(1/2)=τ_0^(1/2)+(η_PL y' )^(1/2) (1) Where τ is the shear stress measured …

An Alternate Dimensionless Form Of The Linearized Rigid-Body Aircraft Equations Of Motion With Emphasis On Dynamic Parameters, Douglas F. Hunsaker, Benjamin C. Moulton

Mechanical and Aerospace Engineering Student Publications and Presentations

The equations of motion for an aircraft can be linearized about a reference condition within the assumptions of small disturbances and linear aerodynamics. The resulting system of equations is typically solved to obtain the eigenvalues and eigenvectors that describe the small disturbance motion of the aircraft. Results from such an analysis are often used to predict the rigid-body dynamic modes of the aircraft and associated handling qualities. This process is typically carried out in dimensional form in most text books, or in nondimensional form using dimensionless parameters rooted in aerodynamic theory. Here we apply Buckingham’s Pi theorem to obtain nondimensional …
