A testimony to the progress made in CFD has been its widespread use in animated motion pictures. The emphasis here is on a realistic animated rendering of fluid flows for cinematic depiction rather than on performing accurate technical predictions. However, several innovations introduced here have a general applicability and may grow to involve more traditional fluid dynamicists in the coming years. The highly engaging textbooks by Stam (2016) and Bridson (2016) summarize the methods used and the current state of practice in this area. Various such works with a strong CFD component have received academy awards (scientific and technical) for motion picture animations (e.g., the Industrial Light & Magic (ILM) Fluid Simulation System (2007), Autodesk Maya Fluid Effects System (2003, 2005, and 2008)).

Since there is no formula for calculating the fluid velocity and particle velocity in Falcon at this stage, this section uses the CFD simulation result as the calculation result of the formula. With the development of computer application, numerical simulation has been regarded as a effective measure to achieve the study of flow field, accordingly, CFD (Computational Fluid Dynamics) is one of the fluid simulation method (Zhang 2004). For example: Delele et al. (2016) used CFD model to show solids and fluid flow behavior in rotary drums (Delele et al. 2016); Farzanegan et al. (2017) reported that two-phase flow in flotation column was researched based on CFD simulation; Kartashev, Kartasheva, and Terekhin (2017) studied multiphase Flowmeter Flow Path by using CFD numerical simulation. Jiang et al. 2019) reported that a detailed study of oil-water flow in the CAF generator device and effects of variation of gap thickness based on CFD simulation. In this study, Fluent software was selected to simulate field flow to obtain velocity distribution characteristics in Falcon separator.

In another attempt, we decided to have our approach compared with Fisas’s approach in the scope of computer graphics. The related corpus which is called Dr. Invertor corpus5 (DRI corpus) consists of 40 papers in the area of computer graphics and has been annotated by 3 computationally oriented linguists. The whole dataset has been divided into four subgroups each of which contains 10 papers and concerns a specific field in computer Graphics; these include ‘Skinning’, ‘Motion’, ‘Fluid simulation’ and ‘Cloth simulation’.

Huber (2011) presented a way to simulate the cloth and the fluid that also handles fluid diffusion across absorbent textiles. Based on the cloth simulation engine, he combined the state of the art-finite element with a smoothed particle hydrodynamic (SPH) fluid simulation. He explained the possibility of interaction between the fluid and textile. To prepare a model for fluid transformation across wet cloth, Huber uses Fick’s law of translation diffusion. Fick’s laws of equation are used to compute the diffusion states; it is described as a very fast and discrete cellular automation (Lauterbach et al. 2010; Springel 2010). Decaudin et al. proposed producing virtual cloth depending completely on geometric method. The resulted fabric consisted of developed faces sheets that envelop around a mannequin normal method constructing optically bends. Furthermore, this system supplies stitching models, which is possible to use in deformation-free weave designing and for sewing of actual human life identical to the planned clothes (Decaudin et al. 2006). Mongus et al. (2012) proposed a road to obtain proper behaviour of computer-simulated textiles (e.g. silk, wool, cotton); the physical particularities disfigure when enabled to hang under its own weight and are usually measured using a drape meter. Cloth and fluid simulation represent one of the most important and effective aims in computer graphics world (Decaudin et al. 2006). Where recent years has a large advance in simulation of wet cloth, however, the majority of studies focused on the underwater cloth simulation. Chen et al. (2012) produced one of the most important approaches to simulate the cloth under wet influence. In this technique there is simulated wet garb for virtual human with realistic crease and bends. The unique characteristic of this work is the wrinkle and friction pattern. In our work, we present a method to illustrate the behaviour of cloth when it is been under the impact of external effects such as wet, gravity and wind (Saba & Rehman 2012a; Rehman & Saba 2014).
