Annotation: The sphere of gaming software development is actively developing today. Gaming software has in its structure and complex algorithms, and highly loaded multi-user servers, and transaction systems. Modern games are aimed at long-term retention of the player, therefore, they use various methods, thereby attracting users to spend a lot of time in the game, make progress and even make financial investments to obtain additional privileges in the game world. An important role in the development of gaming software is played by the safety of product data and its users, since any data leak or illegal use of it can cause both financial and moral damage to users and the developer company.

Annotation: In computational fluid dynamics (CFD) spray dryers, the Euler-Lagrange model is used to calculate the motions of sprayed droplets and heat and mass transfer between droplets and airflow. Such calculations are performed for hundreds and tens of thousands of droplets representing spray in the dryer. One of the limiting factors in drying mass transfer is the diffusion of moisture within the partially dried particles. To simulate this internal diffusion of moisture, each particle is represented by a series of concentric spherical shells. For these shells, a one-dimensional diffusion equation is solved to obtain the internal distribution and diffusion of moisture within each particle. A key advantage of CFDs is the ability to quickly analyze potential options and optimize. As an example, we considered a dryer with a given set of conditions for supplying the product and the heat carrier. CFD simulations were carried out in order to find the optimal conditions for the heating air. Key information of interest to the plant operator can be extracted from the CFD results and presented in trajectories by a visual representation of particles leaving the drying plant. Based on these results, the dryer operator can easily select the optimum operating conditions to achieve the desired product quality at the lowest cost.
