"In this comically far-fetched book, a talented gorilla’s paintings of other zoo animals and their visitors earn her fame and fortune, which she’s not sure what do with.... In the end, this joyful painting gorilla reminds us that the best things in life are free." --Publishers Weekly

This is my end of year project. Archetypes In Flux is my journey/portfolio of my first year at London Metropolitan University.

Previous investigations of oscillating (harmonic) flow past circular cylinders via the discrete vortex method have met with limited success due to a variety of reasons. These assumptions have proven to be too severe, and cannot allow the prediction of the kinematics and dynamics of the oscillating flow about bluff bodies in general and about a circular cylinder in particular. In the current analysis, the ambient velocity was given by U = Um sin wt, and the velocity distribution and the boundary layer were calculated about the cylinder at suitable time intervals. Several methods were implemented to predict separation, all of which required a minimum of arbitrary assumptions. Nascent vortices were placed at the separation points in such a manner that the Kutta condition was satisfied. Several functional forms of dissipation were investigated, but it was found not to be of overriding influence in the flow kinematics. Counter vortices were found to be a necessary aspect of the analysis, providing continuity from one half cycle to the next. Flow visualization experiments were conducted for a Keulegan-Carpenter number of 10 as a basis for comparison. The kinematics obtained from the numerical model produced a vortex shedding pattern which was typical of those observed experimentally for higher Keulegan-Carpenter numbers. Significant problems were encountered in the prediction of boundary layer separation. At this point, it was obvious that the interaction of a vortex with a boundary layer warranted analysis in a much simpler flow situation; the blade-vortex interaction (BVI) problem proved to be ideal.

Accidentally activated in a future world where only the savage survive, a life-size toy named Fred is programmed to be a friend and spread kindness and good will wherever he goes, but in this world that is going to be difficult--so Fred decides that his first task is to get Lord Bonkers and Papa Mayhem, two warlords, to make peace and become friends.

When Fred, a kindhearted robot, discovers a hidden post-apocalyptic paradise whose leader refuses to share its resources, a shocking glitch turns him mean, forcing him to confront his own nature before he undoes all the good he has built.
