In this project, self-build CFD code in C++ is employed to simulate several classical
fluid dynamic, heat and mass transfer problems such as Driven Cavity, Deferential
Heat Cavity, Square Cylinder problem. Besides, this work also includes a code of
absorption chiller in condition of falling film, and the result of the code will be
compared with previous work of other researchers.
The inform consists of 6 chapters. Chapter 1 is introduction where the objective and
scope is explained. In chapter 2, the govern equation of both mass, momentum and
energy equation will be deduced at different conditions using different hypothesis and
simplification. In chapter 3, the discretization of the govern equation and the mesh of
the domain will be carried out. In chapter 4, the algorithm of fractional method step
will be explained and, also the algorithm for the falling film. In chapter 5, the result of
each corresponding code will be compared with high resolution benchmark result. In
the final chapter 6, an experiment of component of absorption chiller with falling film
of aqueous LiBr driven by gravity is carried out. The experiment should be operated
in vacuum condition at absolute pressure around 1000 Pa, but no experiment data is
acquired due to the lack of time. The information of experiment apparatus will be
demonstrated in the annex.
