Elliptisk brandzone udbredelse: Model

Model med konstant vind

x ( t , φ) = a · t · cos (φ)

y ( t , φ) = b · t · sin (φ) + c · t

(23)

Elliptisk brandzone udbredelse: Model

Denition

v = b + c (Medvinds-farten)

u = a (Flanke-parallelvinds-farten)

w = b − c (Modvinds-farten) ,

(24)

Elliptisk brandzone udbredelse: Model OK iht. CFFBPS

"The Canadian Forest Fire Behaviour Prediction System

(CFFBPS) assumes elliptical growth and has documented values

of u, v, and w for a very large set of constant parameters

aecting a re. It has also been observed that, within certain

limits, the ratio a / b is a function of wind speed only; this is also

an assumption of the CFFBPS."
