Objective: `(delu)/(delt) + C(delu)/(delx) =0` To solve the above mentioned 1D Linear Convection Equation using Finite Difference Method where forward differencing is used for the time derivative term and backward differencing is used for the space terms. The initial velocity and the final velocity is to be compared for…

Objective:  In Engineering, ODE is used to describe the transient behaviour of a system.  A simple example is a pendulum   The way the pendulum moves depends on the Newtons second law. When this law is written down, we get a second order Ordinary Differential Equation that describes the position of the "ball"…

Objective:  The main target is to find the 4th order approximations of the 2nd order derivative of the function f(x) = exp(x)*cos(x) using all the 3 numerical approximations methods namely, Central Difference Method, Skewed Right-Sided Difference Method and Skewed Left-Sided Difference Method. Then we need to compute…

Objective: Stoichiometric combustion offers an easy way to understand combustion concepts. When fuel and air mix they produce products as CO2, CO, OH, H2O, NO, N2O and many more. In stoichiometric combustion, we make a simple assumption that the by-products are only CO2, H2O and N2. For a generic alkane fuel, the combustion…

Objective:  To solve a heat conduction equation of a 2D plate surrounded by constant temperature by Finite Difference Method. Here we will consider both the steady-state and transient cases and compare by which iterative method results with better accuracy with less number of iteration can be obtained. Also, we will…

Objective: To find the significance of Spectral radius on the converge and stability of a linear system Theory:  The solution of a system of linear equations can be found by implementing the iterative solvers namely, Jacobi, Gauss-Seidal and SOR. However the before starting to solve a system, we can predict the…
