By the considering fire pump and monitor capacity within dynamic environment (adjustable wind parameter and monitor angle/direction), a water spraying CFD simulation model will be established. The developed model should calculate falling water volume and quantity to fire area after the exit from adjustable fire monitor. As well as CFD simulation model creating, the freelancer also should drawn model geometry similiar to given technical design for fire pump and monitor, a basic document include selecting mathematical expression-formulation, initial and boundary condition detail, assumptions.
