Humpback whales have very special fins, which reduce the friction force by projections on fins and enhance lift with increasing angle of attack. Thus, it has opportunity to move less energy. In this study, tubular structure was formed adapted NACA0012 airfoil profile. Numerical modelling tubercle wing performed in ANSYS FLUENT. numerical modelling, k-ω SST Transition turbulence models were used...

The roadway deformation normally relates to time especially for underground coal roadway. strength of soft is low, and therefore the increases gradually under constant stress with time, which called rheology deformation. In this study, based on a field case, rock mass properties data were obtained according test. A 3D numerical model was then established, rheological including horizontal vertic...

Oil injected screw compressors are commonly used in the industry. The position and amount of oil injection determined experimentally or by heat balances with an assumption uniform distribution compression chamber, which is not validated. This paper presents a study on within compressor chamber using Computational Fluid Dynamics (CFD) Volume (VOF) multiphase model. Prerequisite for CFD body fitt...

Barite stands out as one of the most ubiquitous scaling agents in deep geothermal systems, responsible for irreversible efficiency loss. Due to complex parameter interplay, it is imperative utilise numerical simulations investigate temporal and spatial precipitation effects. A one-dimensional reactive transport model set up with heterogeneous nucleation crystal growth kinetics. In line systems ...

In order to enhance retention of particulate and colloidal (organic) matter, chemical coagulation (CC) is often used prior pressure-driven membrane filtration. This combined hybrid system may be a potential solution for environmental problems dealing with drinking water treatment, reuse, rational waste management. this study, an EC reactor spiral electrodes was investigated numerically, focusin...
