“…The authors suggest that this approach could optimize the apparatus construction to eliminate dead zones and intensify mass and heat exchange between a boiling liquid and solid wall. Currently to perform boiling simulations, Euler-Euler [42,44] or Volume of Fluid (VOF) [43] models with different extensions are being used. To describe bubble flow, the Algebraic Interfacial Area Density (AIAD) and Generalised-Two-Phase (GENTOP) models could be implemented in CFD calculations.…”

The popularity of beer and the complexity of its formation call for simulating and optimizing the operations that take place during brewing in order to reduce energy costs, minimize the consumption of raw materials, maximize the use of equipment, and produce a product of the best possible quality. In recent decades, noteworthy progress has been made in understanding the phenomena occurring in various industrial devices thanks to Computational Fluid Dynamics (CFD). This article is a review of previous attempts to use CFD methods to understand and simulate the processes that accompany individual stages of beer production. Additionally, the paper indicates the possible use of CFD methods for processes that have not been modelled yet in the brewing industry.

The heat transfer system of the pipe for furnace application was newly introduced and need to be analyzed. The study aims to numerically model and investigate the externally blown heated pipe for furnace. The furnace itself is the heat source for briquette production inside the oven. The investigation includes the analysis of temperature, air flow velocity and also pressure inside the pipes. The investigation employed the Computational Fluid Dynamics methodology for numerically analysis the intended results. Three cases were introduced in this study, having differences in the air intake velocity which was set to 5 m/s (case 1), 3 m/s (case 2) and 1 m/s (case 3). The main objective is to have the highest outlet temperature to be blown in the heating chamber. Case 1 results in the lowest resulting temperature which only 77 , while case 3 yields in the highest output temperature more than 100 . In terms of velocity, it is clear that the highest velocity intake affects also in the increasing value of the velocity inside the pipe. Case 1 results in maximum of 35 m/s air velocity. The pressure distribution also results in the similar trend. The case 1 yields in the maximum pressure of 650 Pa and case 3 produce the pressure nearly zero. However, case 3 results in the highest temperature for furnace to be blown in the heating chamber of the oven system.

“…1 Numerous published papers delved into the analysis of the boiling process, employing CFD simulation to study the mechanisms such as predicting phase change behavior, analyzing bubble dynamics, optimizing heat transfer surfaces, and improving system design. [9][10][11] Pothukuchi et al 12 performed a CFD simulation to determine the critical heat flux (CHF) location and the value in three distinct geometries: a tube, an annulus, and a rod bundle. Zhang et al 13 utilized FLUENT software to perform a CFD simulation of an external reactor vessel cooling (ERVC) channel.…”

This paper presents the pool boiling process of argon atoms on the copper surface by employing molecular dynamics simulation. Through the application of molecular dynamics simulation, this study explores three cases: the plain surface, and adding platinum and aluminum nanoparticles to the argon fluid. The main objective is to offer a comprehensive comparative analysis to highlight the significance and innovation of this research. The investigation aims to assess the effectiveness of two methods for improving heat transfer: the addition of nanoparticles to the base fluid and the creation of porous nanostructure. By subjecting these approaches to identical simulation conditions, an enthralling evaluation unfolds. The simulation framework is first validated, and then the results are presented and compared with the case of creating porous geometry. The results reveal that while the evaporation rate has a similar impact in both cases, creating porous geometry results in a 3.68% higher argon temperature compared to adding nanoparticles. On the other hand, adding nanoparticles enhances the maximum heat flux by approximately 15% more than creating porous geometry. This research compares two approaches to offer valuable investigations and insights into enhancing heat transfer efficiency due to the growing demand for strategies that promote heat transfer.
