Mathematical modeling of
wind flow and transport of
pollutants in order to predict
the ecological situation in
residential areas
Speaker: Nygmetova Assem
Speciality: Mathematical and computer modeling

Head of research
work
Issakhov Alibek, PhD doctor, professor
Purpose: Development and application of mathematical
models of wind flow and pollutant transport to predict the
level of air pollution in a certain quarter of Almaty,
Kazakhstan.

3.

The relevance of research: The mathematical modeling of wind flow and pollutant
transfer is critical for creating a sustainable and healthy living environment in
residential areas. It informs decision-making processes, facilitates urban planning, and
contributes to the development of effective environmental policies and regulations.
