“…The integration of CFD simulation results into AR/VR has been investigated following two main approaches to process CFD datasets: re-processing text-based CFD data extracts in the game engine (Berger and Cristie, 2015) and integrating CAD-based 3D visual post-processing extracts with the game engine (Zhu et al, 2019). Several studies have also proposed the update of results in the AR/VR environment by using dedicated cloud servers (Fukuda et al, 2019;Kim et al, 2018). Another study reviewed engineering simulations in AR from a broad perspective (Li et al, 2017).…”

Engineering simulations have opened several gates for today's chemical engineers. They are powerful tools to provide technical content as physics-based numerical solvers. Augmented reality (AR) and virtual reality (VR), on the other hand, are already underway to digitize environments in many fields. The combination of AR/VR environments and simulations in engineering education has been attracting widespread interest. Literature has demonstrated a massive amount of educational digital environments in several contexts as being complementary to conventional educational methods. Nevertheless, hosting technical content produced by engineering simulations with educational AR/VR is still challenging and requires expertise from multiple disciplines throughout the technical development. Present work provides a facile and agile methodology for low-cost hardware but content-wise rich AR software development. A case study is developed to teach chemical-engineering concepts using a liquid-soap synthesis process. Accordingly, we assess and conclude the digital development process to guide unexperienced developers for the digitalization of teaching content. The present contribution serves as an example of the power of integrating AR/VR with traditional engineering simulations for educational purposes. The digital tool developed in this work is shared in the online version.

“…11 The constant increase in computational power (CPU and GPU) gives today the possibility to modify some parameters ''on-the-fly,'' like in flow simulations, based on CFD (computational fluid dynamics). CFD is a combination of physics and applied mathematics, 12 that allow the calculation of gas or liquid flows, and much commercial software (e.g. ANSYS Fluent, Paraview) exist today to address issues such as ventilation inside a vehicle or the behavior of air flows in a room.…”

“…7 To represent air quality, visualizations are frequently based on particles, as the concentration can be visualized by color or opacity. Colors typically range from blue to red to reflect quality degradation, 12 and similarly higher opacity indicates high concentration. 13 In this perspective, we can mention the volumetric rendering approach based on voxels, used for example to visualize interpolated pollen values, 9 rock fracture patterns based on acoustic emissions 10 or geovisualization of COVID-19 data 26 and which can be applied to air quality visualization.…”

This study presents two experiments addressing the representation of scientific data, in particular airflows, with a user-centered design approach. Our objective is to provide users feedback to data visualization designers to help them choose an air flow representation that is understandable and attractive for non-experts. The first study focuses on static markers allowing to visualize an airflow, with information characterizing the direction and the intensity. In a second study, carried out in an immersive virtual environment, two information were added, the temporal evolution and the concentration of pollutants in the air. To measure comprehension and attractiveness, participants were asked to answer items on Likert scales (experiment 1) and to answer User Experience Questionnaire (experiment 2). The results revealed that arrows seem to be a very common and understandable form to represent orientation and direction of flow, but that they should be improved to be more attractive by making them brighter and more transparent, as the representation could occlude the scene, especially in virtual reality. To solve this problem, we suggest giving the users the ability to define the specific area where they want to see the air flow, using a cross-sectional view. Vector fields and streamlines could therefore be applied in a virtual reality context.

“…The main disadvantage of the methodology is that only support of cloud computing is considered whereas other network possibilities were dismissed. Similarly, Kim et al proposed a framework built upon the CFD simulation, AR post-processing, and AR visualization together with devices and cloud servers [17].…”

Computational fluid dynamics (CFD) simulations can provide meaningful technical content in engineering education, broad engineering and business. However, computationally demanding data production and complex data processing environments of CFD simulations turn them into esoteric tools for potential nonexpert users. This consequently limits applications and communications of CFD simulations and results. Augmented and virtual reality (AR/VR) technologies are opening new gates for visualization and interaction techniques. Despite the many recent attempts, the literature lacks an inclusive system development procedure for CFD simulations with AR/VR. The present study proposes a componentoriented system architecture to generate dedicated workflows for any kind of AR/VR environment supported by CFD simulations. The study further explores the potential of data processing options throughout the preparation of the simulation dataset with AR/VR. An automated data coupling strategy is additionally introduced to ease multiplatform integration. We provide an integration strategy with simple, easy-to-implement, end-to-end, automated and free-to-use utilities that the practitioners can readily pursue.
