“…Hot and humid conditions in poultry houses adversely affect bird welfare and productivity [52,68]. As temperatures and humidity rise, heat stress becomes a problem, resulting in reduced feed intake, lower meat/egg production, and increased mortality [69]. To overcome these challenges, it is critical to implement sustainable ventilation designs that can maintain an optimal thermal environment for poultry.…”

In recent years, computational fluid dynamics (CFD) has become increasingly important and has proven to be an effective method for assessing environmental conditions in poultry houses. CFD offers simplicity, efficiency, and rapidity in assessing and optimizing poultry house environments, thereby fueling greater interest in its application. This article aims to facilitate researchers in their search for relevant CFD studies in poultry housing environmental conditions by providing an in-depth review of the latest advancements in this field. It has been found that CFD has been widely employed to study and analyze various aspects of poultry house ventilation and air quality under the following five main headings: inlet and fan configuration, ventilation system design, air temperature–humidity distribution, airflow distribution, and particle matter and gas emission. The most commonly used turbulence models in poultry buildings are the standard k-ε, renormalization group (RNG) k-ε, and realizable k-ε models. Additionally, this article presents key solutions with a summary and visualization of fundamental approaches employed in addressing path planning problems within the CFD process. Furthermore, potential challenges, such as data acquisition, validation, computational resource requirements, meshing, and the selection of a proper turbulence model, are discussed, and avenues for future research (the integration of machine learning, building information modeling, and feedback control systems with CFD) are explored.

“…The velocity field can express in detail the operation law of a variety of velocity vectors in the fluid, which provides an important basis for the evolution of the fluid flow state. Elghardouf et al 12 modeled and analyzed the influence of negative pressure on airflow and found that a negative pressure difference could enhance the change of the air flow rate. Qiu et al 13 used a deep learning framework to predict the velocity field of pumping thrusters, and they better demonstrated the change law of the jet velocity field.…”

A jet impingement-negative pressure deamination reactor (JI-NPDR) has excellent ammonia removal efficiency. The CFD numerical simulation method based on the Euler−Euler model and the realizable k−ε turbulence model was used to investigate the effect of different negative pressures at the reactor top outlet on the distribution pattern of pressure, velocity, turbulent kinetic energy, and vortex. The results indicate that the overall water flow distribution in the reactor increases in axial cohesion with the increase in negative pressure. The scattered small eddies gradually connect to a large eddy current as a whole, and the small eddies generated in the jet area also become regular and flat with the increase of negative pressures. These findings can provide detailed information for the study of flow patterns in a jet impingement-negative pressure reactor.
