- Overview about the project:
my project is to investigate the dust flow and concentration at different points in outdoor space of small community before and after adding different types of trees as buffer zone around the community.
the dust is presented as PM10 which is any particles less than or equal to 10 micrometers in diameter , these particles are one of the major pollutants in the air and have many bad effects on human health.
first i want to clarify that PM10 are solids but once they are lifted by the air they are converted from a static solid-like state to a dynamic fluid-like state under the phenomena of fluidization.
the study area surrounded by desert from three sides, which i will consider as the source of the dust in my simulation.
i will simulate the windest day in three months before and after adding three types of plants where i will define the wind speed and direction in that day as will as the dust flux value as measured in the field in microgram/m2/s.
my questions are:
1- is incompressible analysis with k-omega SST Turbulence model/ Steady state / 1 Passive species, the right simulation?
2- what is the right way to define dust as passive scalar and the 3 surrounding area as the source of dust
3- how can i define the trees as porous media
4- is the program capable to present the dust concentration values and distribution in the results ?
i did a test simulation but all the results were showing only wind
thank you for your help,
