Dear Team,
Can you help me solve a system of ODEs ( Ordinary differential equations):
Can you help me solve a system of ODEs ( Ordinary differential equations):
d/dt(q_d1)=cons_d1(1-q_d1) ; q_d1(at t=0)=0
d/dt(q_d2)=cons_d2(1-q_d2) ; q_d2(at t=0)=0
d/dt(q_r)=cons_r(1-q_r) ; q_r(at t=0)=0
q_d = (q_d1+q_d2)/2;
%% Constants %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
theta = 353; % absolute temperature in Kelvin
c_small = 1; %homogenous oxygen penetration
R = 8.314; % universal gas constant in J/mol %
nu_d1 = 5.3955e6; % in /sec
E_d1 = 8.9732e4; % in J/mol
cons_d1 = c_small * nu_d1 * exp(-(E_d1 / (R * theta)));
nu_d2 = 5.401e7; % in /sec
E_d2 = 1.0361e5;
cons_d2 = c_small * nu_d2 * exp(-(E_d2 / (R * theta)));
