TMA is the species which is emitted in a closed fish market assuming from above image. so assuming TMA is the species emitted from a closed fish market. I encountered a crazy idea, to simulate the distribution of TMA with respect to the flow field in the closed fish market. basically i dont have any experimental data or past simulations similar to the following link. https://www.simscale.com/projects/vaibhav_s/pollutant_extraction_from_parking_garage_-_editorial_demo/
in the above link, the editor explained the source generation rate or calculation of volumetric source generation rate for the entire car park based on number of cars.
in a similar way, i assume x number of similar fish present in a closed fish market which will be emitting TMA per each fish. if this is the case , can any one please suggest a good article to calculate the ppm in a closed fish market to track the TMA ppm concentration.
if the above approach is not possible, i am thinking to solve atleast in this way
here is the project link
in this case the editor simply added the diffusion coefficient and showed the distribution of species into atmosphere. i am thinking to simulate in this way if the first way is not possible. now i came up with a challenge. wherever i have a group of fish on the table is available, i am thinking to define this surface as a source generation, however i have to define the velocity on that fish group surface. practically this is not a physical velocity surface. so is there any other way to assign the surface with species emission (at a group of fish) with out velocity addition on the surface.
maybe a bit complex or ambiguous. looking forward to hear from the peers. thanks for your time and consideration.
