mathematics at a deeper level. Review of homogeneous equations The homogeneous constant coefficient linear equation an y (n) +· · ·+a1 y +a0 y = 0 has the characteristic polynomial an rn +· · ·+a1 r+a0 = 0. From the roots r1 ‚ . . . ‚ rn of the polynomial we can construct the solutions y1 ‚ . . . ‚ yn ‚ such as y1 = er1 x . We can also rewrite the equation in a weird-looking but useful way‚ using the symbol d D = dx . Examples: equation: y − 5y + 6y = 0. polynomial: r2 − 5r + 6 = 0. (factored):

one-dimensional‚ one-phase flow equations As an introduction to reservoir simulation‚ we will review the simplest one-dimensional flow equations for horizontal flow of one fluid‚ and look at analytical and numerical solutions of pressure as function of position and time. These equations are derived using the continuity equation‚ Darcy’s equation‚ and compressibility definitions for rock and fluid‚ assuming constant permeability and viscosity. They are the simplest equations we can have‚ which involve

Mathematical models can take many forms‚ including but not limited to dynamical systems‚ statistical models‚ differential equations‚ or game theoretic models. These and other types of models can overlap‚ with a given model involving a variety of abstract structures. Examples of mathematical models Population Growth.

(Eq 2) Equations (1) and (2) are interrelated‚ and this can be demonstrated through modeling a basic electrical circuit involving a second order‚ linear differential equation. For our basic circuit‚ we will use a single closed loop involving one voltage source‚ one resistor‚ one capacitor‚ and one inductor. First‚ it is important to establish
