The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....
The simplified equations of motion proposed by Morton to determine
the extent of vertical travel of a forced plume in a linear
density stratified environment were re-written and solved in a way
which allowed them to be applied to any non linear profile of density.
For application to any specific...
Transition phenomena commonly occur in nature. These arise
either due to structural or behavioral changes in the medium. Examples
for these abound in all applied sciences and to mention a few
of these, we have, boundary layer, elastic-plastic deformation, and
shocks. The present work is devoted to the study of...
The last two decades have seen many new continuum models for
electromagnetic materials which were constructed by merely adding
terms to the classical balance laws and constitutive equations. Nonlocal
theories, such as the one developed by A. C. Eringen., however,
depart from the traditional approaches by accounting for the effects...
An introduction to the generalized measures of deformation-
rates involving not only velocity gradients but also
acceleration gradients is given and constitutive equations
using these measures have been discussed. These new constitutive
equations are then used to study torsional
flows of viscoelastic fluids between two infinite parallel
planes. In order...
The problem of a general incompressible viscous fluid flow past
a flat plate with heat transfer due to forced convection is considered
in this thesis. The synthetic method developed by B. R.
Seth is applied to the Navier-Stokes equations and the equation of
energy governing the flow to obtain the...
Our studies and those of our colleagues in Idaho indicate that the western Snake River Basin is a major geothermal province, similar in some ways to the Imperial Valley Geothermal Province. Deep drilling should encounter high temperature fluids in permeable rocks below 2 km and at shallower depths where permeability...
The asymptotic boundary layer problem involving an axial
incompressible Newtonian fluid flow past a circular cylinder parallel
to its axis was investigated by Stewartson (1955). He addressed hiself
primarily to the Mangler's (1948) derivation, namely, the
character of the boundary layer on a circular cylinder is equivalent to
that on...
