Moreover, in his study, SST Kω model is capable of predicting the accurate velocity profile charts as acquired from experimental study. Menter study, it is noted that the SST Kω model outperforms and predicts the reduction of kinematic eddy viscosity quantity due to the adverse pressure gradient profiles in very good agreement for all x-station of a flat plate with that of the experiments. Now keeping in mind our application, i.e., related to aerospace industry, Menter’s shear stress transport (SST) model initially developed by F.R. Moreover, to determine the forces and moments in a wind tunnel, several pressure orifices are required and mounted over the model of interest to determine the pressure distribution on the surface of the model, due to which it is hard to set up the experiment as compared to CFD. However, wind tunnel experiments are expensive to conduct, and their real flow characteristics are hard to analyze due to the limitation of size of the test section for which scaling down of the geometry is required. As far as the visualization of flow is concerned, CFD helps in depicting pattern of the fluid flow, which is difficult with regular wind tunnel experiments. + ∂ ∂ x k ∂ T ∂ x + ∂ ∂ y k ∂ T ∂ y + ∂ ∂ z k ∂ T ∂ z − ∂ up ∂ x − ∂ vp ∂ y − ∂ wp ∂ z + ∂ u τ xx ∂ x + ∂ u τ yx ∂ y + ∂ u τ zx ∂ z + ∂ v τ xy ∂ x + ∂ v τ yy ∂ y + ∂ v τ zy ∂ z + ∂ w τ xz ∂ x + ∂ w τ yz ∂ y + ∂ w τ zz ∂ z + ρf × V E5ĬFD is a cost-effective and easy to use method which empowers engineers to virtually simulate and visualize the experiments carried out using wind tunnels.This effort will inline flight organizations to act according to the ICAO Programme of Action on International Aviation and Climate Change, which enforces the ways to save material cost, i.e., fuel economy, and protect the environment which are the key concerns that can be a driving factor for designing flight simulators. Moreover, the need of designing a realistic FDM for flight simulators can also reduce the amount of actual flight time pilots put on aircrafts by which fuel and CO 2 emission can be saved. In line with the above, it is significantly necessary to train new pilots from a realistic approach, keeping in mind the existing piloting reviews from old fellows of that aircraft to adopt for a dynamically changing environment whether that be in terms of standard operating procedures (SOPs) of flight, systems, or navigation. For this reason, high-fidelity FDM is a concerning aspect. As the hiring and training of new pilots is expensive, for this reason internationally, ground training with respect to particular aircraft is being catered by flight simulators. The current dire need of flight simulators is captured from the high rate of hiring of new pilots and indulgence of the airlines whether it is in Pakistan or international forum. It’s a question of interest, why one should design FDM?, because the FDM is a heart for flight simulator.
