Nature has been perfecting flight much longer than any human. By studying the myriad of ways these creatures achieve this, engineers can build more efficient and dynamic flying—or even swimming—drones. These drones may one day deliver groceries to your front door or plumb the depths to study ...
Cavitation is undesirable because it produces extensive erosion of the rotating blades, additional noise from the resultant knocking and vibrations, and a significant reduction of efficiency because it distorts the flow pattern. The cavities form when the pressure of the liquid has been reduced to ...
This method uses a set of conservation equations for each bubble class, accounting for bubble breakup and coalescence. In the Eulerian-Lagrangian approach, the liquid phase is treated as a continuum. In contrast, the dispersed phase is determined by using a Lagrangian approach in which newton's ...
Typical buildings are static structures, unable to adjust to dynamic temperature and daylight fluctuations. Here, authors present an adaptive alternative, using shape-tuneable pigment injections to control solar ingress and reduce estimated building energy use by 30%. ...
Physics-informed neural networks (PINNs), another class of algorithm, are gaining ground since they add physical intuition in common NNs, and can bind experimental data with Navier–Stokes equations for fluid mechanics [140,141,148,149,150]. Algorithms based on genetic programming (GP) are best...
For this particular class of multi-phase flows, we consider the solid particles and gas bubbles as being the discrete constituents of the dispersed phase co-flowing with the continuous liquid phase. The co-existence of three phases considerably complicates the fluid flow due to an array of ...
Investigating and tailoring the thermodynamic properties of different fluids is crucial to many fields. For example, the efficiency, operation range, and environmental safety of applications in energy and refrigeration cycles are highly affected by the p
ELGi North America announced the launch of the Airmate HLD series modular desiccant compressed air dryer, a state-of-the-art solution for applications that demand ultra dry compressed air. Engineered to achieve ISO 8573-1:2010 Class 2 compressed air quality, the new desiccant air dryer consistentl...
Further, as a result of these conditions of application, drilling fluids are inherently dynamic; “living” fluids that change constantly as they interact with the formation and bit, incorporate drill solids, absorb formation fluids and gases, and cycle through dramatic changes in temperature and ...
