Diffusion Simulation Plot - Concentration Gradient Visualization #2064088 (License: Personal Use)

This image depicts a numerical simulation of diffusion, where a green circular region represents a high-concentration zone, enveloped by a blue gradient indicating decreasing concentration. A horizontal blue bar intersects the circle at its center, suggesting a boundary condition or flux channel. The axes suggest spatial coordinates in arbitrary units, typical of finite-difference or finite-element modeling outputs.

Used in computational physics, chemistry, or biomedical engineering webpages to illustrate diffusion phenomena, reaction-diffusion systems, or drug delivery modeling; targets researchers, students, and educators seeking visual explanations of PDE-based simulations.
