My geometry consist of a simple 18 mm diameter spherical pellet with a initial concentration of the magnetite 6.8941 Kmol/m3 and carbon being 22.54169 Kmol/m3. These initial concentration when converted comes up to magnetite 0.2342 and carbon 0.7658 as mole fraction on manual calculation. so i just initialized it as shown in the second figure and started the simulation.
I have given an volume average of molar concentration of each species as shown in figure 3 as results.
Now the problem i am facing :
if u notice here the initialized mole fraction of 'm' and 'c' are 0.2342 and 0.7658 but on result plotting the starting point of c Kmol/m3 are 0.036 and m is a very low value. Why is it coming so it should match what is being entered rt ? I cant find y is it happening so Kindly help me out with this
figure-3 where h- hematite m-magnetite w-wustite c-carbon etc
