Abstract: | A rotationally constrained forest fire model is studied on square and triangular lattices of size 400×400. The critical probabilityp
c
for onset of fire propagation is determined. The scaling relationsM t
d
r, Rg tv andM R
g
d
f are analysed at fire propagation probabilityp=p
c
whereM is the number of burnt trees,R
g
the radius of gyration andd
f
the fractal dimension of the cluster of burnt trees at timet. Numerical estimates ofd
t, v andd
f
have been obtained. |
