The Aims of the Project

Estimating Evaporation from Water

Surface

Water Body (WB)

Atmospheric Boundary Layer

(ABL)

Water Body (WB)

• Heat Storage (Budget)• WB’s Properties

(Shape,Turbidity, Fetch, etc.)• Water Flow & Heat Transfer• The Effect of Meteorological

Parameters and Surroundings

Measurement ?or

Simulation?

CFD-WB

• CFD : Computational Fluid Dynamics

Geometry & CFD Computational Grid (Mesh) Lake Binaba

Generated (Final) Bathymetry (stl) of Lake Winkogo

Results (CFD-WB)

Atmospheric Boundary Layer (ABL)• Airflow & Turbulence• Momentum, Mass and Heat Exchange (ABL-WS)• Heat and Mass Transfer• Internal Boundary Layer (Roughness, Temperature, Wetness)• Stability Conditions (Neutral, Stable, Unstable)

CFD-ABL• Turbulence Models• Buoyancy Effect

Results (CFD-ABL)

Results (CFD-WB)

Parallel Computing• Model Should be Run in Parallel• Decomposing, Reconstructing, etc.

Parallel Computing

A graphical representation of Amdahl's law. The speed-up of a program from parallelization is limited by how much of the program can be parallelized. For example, if 90% of the program can be parallelized, the theoretical maximum

speed-up using parallel computing would be 10x no matter how many processors are used.
