This attracted Makinde and Animasaun [8, 9] to focus on the case of quartic autocatalysis kind of chemical reaction in the flow of an electrically conducting nanofluid containing gyrotactic-microorganism over an upper horizontal surface of a paraboloid of revolution in the presence and absence of thermophoresis and Brownian motion.
Paraboloid of revolution. -- Rotating a parabola about its axis, one obtains a paraboloid of revolution (Fig.
Their analyses were in turn based upon relationships developed by Sneddon [38] for the penetration of a flat elastic half space by different probes with particular axisymmetric shapes (e.g., a flat-ended cylindrical punch, a paraboloid of revolution, and a cone).
This problem is solved by using an offset system with a main reflector that is a section of a parent reflector, normally a paraboloid of revolution. Offset, single parabolic reflectors, shown in Figure 2, are widely used for very small aperture terminals (VSAT) in satellite communication networks.
With a focal length of 150 inches, the main reflector is a 9.14-meter paraboloid of revolution. The reflecting surface is manufactured from 24 stressed-sheet aluminum panels attached to a rugged space frame.
Then they must be ground to the desired curved shape (usually a paraboloid of revolution or a piece of a sphere).
