Policy on Academic Integrity in CIVE 300

Academic integrity -- doing and getting credit for your own work, not for the work of others, on all assignments and exams -- is an important aspect of honesty. None of us likes to be lied to or cheated. Others, should be able to expect that we are not lying to or cheating them. When you turn in any assignment or exam in this course (lecture and laboratory), it must be your own work, not copied from any other person or any other source (printed or electronic). Accordingly, the CSU Honor Pledge (, with a place for your signature, must be applied to every assignment and exam submitted in CIVE 300. Violation of the Honor Pledge is unethical and immoral and, if you are caught, will result in serious consequences, including failure.

The homework problems in CIVE 300 are assigned to help you learn the fundamental principles and skills of fluid mechanics and to provide you with opportunities to exercise your mind in the disciplines of analysis and synthesis that are crucial to successful engineering. There is no substitute for solving problems in learning these principles, skills, and disciplines.

Working together in groups on homework problems is fine and, when done rightly, can be beneficial. However, if you work in a group do not sit passively by, waiting for someone else in the group to jump-start the solution process. Instead, before getting together, think and jot down notes on your own about the problems and what approach, assumptions, and methods should be applied to obtain a solution. Then, we you get together, actively participate in the discussion. Regardless of whether you work entirely on your own or you participate in a group discussion, you are expected to conduct and write up the homework solutions entirely on your own and to turn them in as your own work. Do not copy solutions from any person or from any other source (printed or electronic).

Computer Models


“Marine stratocumulus clouds frequently form parallel rows, or ‘cloud streets,’ along the direction of wind flow. When the flow is interrupted by an obstacle such as an island, a series of organized eddies can appear within the cloud layer downwind of the obstacle. These turbulence patterns are known as von Karman vortex streets. In these images from NASA’s Multi-angle Imaging SpectroRadiometer, an impressive vortex pattern continues for over 300 km southward of Jan Mayen island. Jan Mayen is an isolated territory of Norway, located about 650 km northeast of Iceland in the north Atlantic Ocean. Jan Mayen’s Beerenberg volcano rises about 2.2 km above the ocean surface, providing a significant impediment to wind flow.

These MISR images were captured on June 6, 2001, during Terra orbit 7808. The entire vortex street can be seen in the top panel, which is a natural-color view from the instrument’s nadir (downward-looking) camera. The area covered measures 365 kilometers x 158 kilometers, and a cloud-clearing effect is apparent at the vortex centers until finally closing on the sixteenth “hole.” The bottom panel is a stereo anaglyph of a portion of the vortex street, compiled using data from MISR’s 26-degree forward and 70-degree backward viewing cameras. This view covers an area of about 183 kilometers x 96 kilometers. Despite the vertical exaggeration afforded by using widely separated angles, the relatively modest height variation in the cloud layer implies a vertically stable atmosphere. To facilitate stereo viewing, the images have been oriented with north at the left.

Fluid dynamicist Theodore von Karman was the first to derive the conditions under which these turbulence patterns occur. Von Karman was a professor of aeronautics at the California Institute of Technology and one of the principal founders of NASA’s Jet Propulsion Laboratory.”
