Mathematical Modeling of Plankton Biomass Dynamics During the Spring Thermal Bar in Kamloops Lake

“…Method for Pressure Linked Equations with Density correction) [9], which is a modification of Patankar's method SIMPLE [17], has been developed. SIMPLED corrects velocity and pressure fields by accounting for the variation in density in the gravitational term in equation (3).…”

“…The thermohydrodynamic submodel includes momentum, continuity, and energy equations and an equation of salinity balance in the lake [9]:…”

On the role of wind direction in the thermal bar dynamics in autumn: A numerical study

“…The 2.5D physical model, expressed in the Boussinesq approximation, reproduces hydrodynamic processes in a large lake and includes the equations of momentum, temperature, salinity, and continuity [13].…”

“…This method assumes that fluid velocity components are determined in the middle points of the cell boundaries and scalar values (water pressure, salinity, and temperature; and eddy viscosity and diffusivity coefficients) are in the center of the mesh cell. The harmonization of the calculated pressure and velocity fields was performed using an original SIMPLED (Semi-Implicit Method for Pressure Linked Equations with Density correction) method for buoyant flows [13], which is a modification of SIMPLE method of Patankar [17].…”

Mathematical Modeling of Hydrothermodynamics of Lake Baikal Waters: Results, Problems and Prospects

“…Исключением являются работы Цыденова Б.О. с коллегами [3], в которых модель гидротермодинамики для поперечного сечения обозначена как 2.5-мерная. В ней система уравнений движения записана для трех компонент вектора скорости, как в негидростатической постановке, однако отсутствуют градиенты давления по продольной координате.…”
