Fluid mechanics is the science and technology of fluids either at rest (fluid statics) or in motion (fluid dynamics) and their effects on boundaries such as solid surfaces or interfaces with other fluids. Definition of a fluid: A substance that deforms continuously when subjected to a shear stress C ...

Introduction to the immersed boundary method
... The fluid is aware of the boundary only through a forcing term. There is no direct boundary condition for the fluid (especially not for the populations). This means that the populations can cross the boundaries without seeing them, but the macroscopic fluid behaves as if there was a boundary. This i ...

... the inside, since the movement would be mainly a jet, forcing a vigorous inner mixing. The process is adiabatic on reasons of the little time available for heat exchange, but not isentropic because of the dissipation in the interior. The equation describing the evolution, assuming a representative t ...

Chapter 1 INTRODUCTION AND BASIC CONCEPTS
... A common simplification in the application of Newton’s laws of motion is to subtract the atmospheric pressure and work with gage pressures. This is because atmospheric pressure acts in all directions, and its effect cancels out in every direction. This means we can also ignore the pressure forces a ...

... In a conductive thermal regime, heat flow is predictable. Diagram 2a shows temperature and heat flow curves for conductive continental and oceanic thermal regimes. Continental heat flow decreases with depth as radiogenic heat decreases, but with radiogenic heat two orders of magnitude less than that ...
