Simulation of a semi-batch
reactor with jacketing, where a 1st order reaction takes place. The system
of ODEs is solved using a 4th order Runge-Kutta routine.
Simulation of a catalyst
decay in a fluidized CSTR for the gas-phase cracking of a light gas oil.
The system of ODEs is solved using a 4th order Runge-Kutta routine.
Simulation of a fixed bed
reactor with axial dispersion, for an isothermal steady state model. The
set of partial diferential equations (PDE's) is solved by the Orthogonal
Collocation method.

A simulation of a bouncing,
heatable box that illustrates dramatically The Second Law of thermodynamics
(the one about entropy). By manipulating the parameters of the simulation
you can illustrate a number of fundamental facts about energy flow.

Solution of a Differential
Equation of form dy/dx=f(x,y). The given function is plotted over the specified
range of x and y values, using the given initial conditions, using a second/fourth
order Runge-Kutta method. Alternatively, the graph of y=f(x) can be plotted.

Calculator This applet will let you calculate the compressiblity
factors using the Trebble-Bishnoi-Salim cubic equation of state. From some
databank, feed in the critical temperature (Tc in K), critical pressure
(Pc in kPa), critical volume (Vc in m^3*kmol^-1), acentric factor (w),
and molar mass (M in kg*kmol^-1). Then enter the temperature (T in K) and
pressure (P in kPa) at which you would like to see your liquid or vapor
fractions. You can use the values of Z obtained to determine volume for
some liquid or vapor state V(s)=Z(s)RT/P. Octavian Micro Development Inc.
OMDI
Mass Calculator The above applet will let you calculate the mass
of a molecule. You can enter a formula in the top field A, and optionally
another formula in the bottom field B. (B should be contained in A if you
want a meaningful fraction result.) The calculator will calculate the mass
of the formulae in AMU, and place what fraction B is of A in the appropriate
field. Octavian Micro Development Inc.
