Abstract
Biological drying has been intensively studied due to high market demand.
Computational fluid dynamics has played an important role in this research.
Besides the physical principles involved, numerous papers have described numerical implementation and all details ranging from geometry to visualization, including boundary and initial conditions and mechanical aspects of drying.
For this study, three different structural grid arrangements composed of millions of triangles are used to calculate velocity, temperature, diffusion, advection, and transient development of the cactus drying process through 1500 s of elapsed time, in a forced drying process using a microwave.
The modeling execution time was a few hours on an AMD-FX(tm)-8120 eight-core processor with Linux Ubuntu 8 OS, 3.10 GHz, 32 GB RAM with 64 bit operating system.
As a result, a numerical simulation is used for the Navier Stokes and energy equation by starting with k-epsilon solution method; and validated with hard data obtained using standard normalization.
