Using Computational Fluid Dynamics To Predict Drag On A Boat Hull, John Howland, Zhaohui (George) Qin, Timothy B. Dewhurst
Using Computational Fluid Dynamics To Predict Drag On A Boat Hull, John Howland, Zhaohui (George) Qin, Timothy B. Dewhurst
The Research and Scholarship Symposium (2013-2019)
For many years Cedarville University’s Solar Boat team has been designing and creating boat hulls. One of the key elements in designing a hull is to decrease the amount of drag or resistance the boat has when moving through the water. Previous mechanical engineering seniors at Cedarville University have attempted to use computational fluid dynamics or CFD to predict the drag on the Solar Boat hull with software called Fluent produced by Ansys. However, they have been unsuccessful due to the complexity when trying to model two phases of flow, e.g. air and water. The project however, was successful in …
The Scholarly Role Of Faculty Advisors In Student Engineering Competition Projects, Gerald M. Brown, Timothy B. Dewhurst
The Scholarly Role Of Faculty Advisors In Student Engineering Competition Projects, Gerald M. Brown, Timothy B. Dewhurst
The Research and Scholarship Symposium (2013-2019)
Engineering faculty advisors at Cedarville University work closely with senior engineering students on the Solar Boat team to improve the boat’s performance each year and continue the team’s legacy of 7 wins in the last 10 years at the Solar Splash Competition. The faculty-student relationships are at times similar to that of a mentor and apprentice, and at other times similar to that of an engineering manager and a team of engineers. This mentor/manager approach allows us to maintain technical continuity from year to year between student teams, develop and maintain an increasingly sophisticated team knowledge base, coach the students …

The Design Of A Mobile, Animatronic Bald Eagle, Eric Burns
Phi Kappa Phi Research Symposium (2012-2016)
Modern animatronics are used as a tool to help engage audiences in realistic and entertaining experiences. Many animatronic figures are dynamic in movement, but static in mobility. The research presented covers the beginnings of mobile animatronic research. An animatronic bald eagle, Opportunity, was designed for that purpose. Animations for Opportunity are generated by integration of Arduino, Pololu Mini Maestro, and Hitec Servo Motors. Arduino receives signals from flex sensors which cause voltage variations when “flexed”. The 1:1 scale, animatronic eagle can be perched on the arm of an “actor” who simulates an eagle’s caretaker. The flex sensors are located within …
