In this Project the comparative analysis of Cellular structures versus the Topology Optimized structured beams been observed and these structures are also been compared to the baseline structures as Solid Rectangular Beam and Hollow Cylindrical Beam.
SIMULATE THE PROCESS OF A FALLING WATER DROPLET IMPACTING ON A FLAT WATER SURFACE, IN A PURE 2-D SETTING
The top boundary as pressure outlet with zero gauge pressure, and with a backflow phase set to air. At t = 0, initialize the system with zero gauge pressure and zero velocity. Use the Laminar model and turn on surface tension modeling. Use default values from the Fluent database for the density and viscosity of water and air, and surface tension for air-water interact.

•Simulations are run with Pressure Based Solver.
AERODYNAMICS OF A 3-D “FLYING SAUCER” IN A CYLINDRICAL VIRTUAL WIND TUNNEL.
Project File
Performed a sufficient number of iterations to ensure that lift and drag no longer trend upward or downward. This can be checked by monitoring the lift or drag as a function of the number of iterations. If the value of lift or drag continues to fluctuate with the number of iterations (which could happen if the actual solution is oscillatory or chaotic in time), take the average over a range of iterations. Alternatively, in that case we allow the option of performing a transient simulation and take the time average of lift or drag.

DESIGN OF EXPERIMENTS FOR THE VOLUME OPTIMIZATION OF SOLID RECTANGULAR BEAM
We are basically minimizing the volume of a solid cantilever beam that is under the influence of a uniformly distributed load along with the thickness at the free end. In this process, we would initially be having a CAD model of a solid cantilever beam with a fixed volume say X. We will minimize the volume to say Y of this beam using n-topology before performing the actual 3-D printing on the beam. Here, we will vary some structural parameters, mainly concerned with the internal layout of the beam, thus making changes to the internal structure of the beam.
SIMULATES THE LEAKING OF NATURAL GAS FROM AN UNDERGROUND VAULT INTO THE OPEN AIR, IN A PURE 2-D SETTING
The lateral and top boundaries are all open to the air. A side pipe is connected to a pressurized reservoir of methane (representing natural gas). This task includes two transient simulations. In both, use the default constant values of density and viscosity from Fluent database for air and methane, and set gravity to the regular g = –9.81 m/s2 in the vertical direction (the “y direction” ). Use turbulence k-epsilon model with default setting. Since both phases are gases, the effect of surface tension can be ignored.
