To Continue with my efforts to provide solutions and information helpful to solve the problems of the Gulf of Mexico crude oil spill – (and map it as I go so that anyone reading this can lookup the pathways for themselves and follow it) –

Yesterday, when I was in my encyclopedia – I read something about diesel that I want to include here and this morning noted the LaPlace equation expressed in spherical coordinate’s that I’m going to lookup online – wikipedia or on the physics equations site that I like –

Laplace’s equation

From Wikipedia, the free encyclopedia

Jump to: navigation, search

In mathematics, Laplace’s equation is a partial differential equation named after Pierre-Simon Laplace who first studied its properties. The solutions of Laplace’s equation are important in many fields of science, notably the fields of electromagnetism, astronomy, and fluid dynamics, because they can be used to accurately describe the behavior of electric, gravitational, and fluid potentials. The general theory of solutions to Laplace’s equation is known as potential theory. In the study of heat conduction, the Laplace equation is the steady-state heat equation.

(and this is the reference from the vol. 5, pp. 728; Encyclopedia Britannica, 1978 – from the entry “Diesel Engine”)

Dual fuel engines –

The dual fuel engine is an internal combustion engine that can be operated as an oil diesel entirely on liquid petroleum or, without any mechanical alterations, can produce its horsepower rating on a combination of liquid fuel and natural, or artificially produced, gas. Liquid fuel is needed to perform the basic function of igniting the gas.

The gas diesel operates on gas as the primary fuel that is ignited by the introduction of a small pilot charge of liquid fuel into the cylinder shortly before the piston reaches top dead centre on its compression stroke. The amount of liquid fuel used in the gas diesel is never more than is needed for the ignition of the gas.

On April 30, 1901, the U.S. Patent Office issued to Rudolf Diesel patents that covered all the essential features of the dual fuel and gas diesel engines. In 1932 patents were issued to Victor Heidelburg that covered the advantages of the higher fuel economy made possible by the higher compression ratios that could be used.

Both patents lay unused until 1940, when the rising price of liquid fuel created a demand for natural gas that could be purchased at a very low rate on the basis of an interruptible contract. With such a contract the engine owner could switch from gas to oil and back again on short notice.

LaPlace Equation – as it applies to three dimensional dynamic time dependent fluid mechanics –

My Note –

Imagine oil and fish.

Imagine Gulf of Mexico volume and currents and oil and fish.

Imagine there is a way to calculate it

gone to take a bath and walk to the store for milk – imagine that.
