At present, software products for numerical simulation of fluid dynamics problems (ANSYS Fluent, Ansys CFX, Star CCM, Comsol, etc.) are widely used. These mainly based on the solution Navier–Stokes equations, most common and computationally easy method solving, which is Reynolds averaging (RANS), further closing system using semi-empirical turbulence models. Currently, there many modeling metho...

The generated heat by the superconducting windings and other parts such as current leads in transformer increases hottest point temperature (HPT) causes high (HTS) to quench. Due properties of windings, reducing HPT is critical importance for stable operation HTS transformer. cooling system transformers, not only provides cryogenic proper superconductors but also responsible dissipating winding...

Winglet dapat memberikan peningkatan dengan moderate cost tanpa violating discated spam limit pengembangan metode untuk desain analisi winglet telah menjadi focus dari ...

In this work, a numerical investigation using Ansys Fluent software is performed to study the flow pattern, indoor thermal comfort, and air freshness generated in full-scale ventilated office room occupied by sitting occupant. The performance of multi-cone ceiling diffuser equipped with lobed inserts assessed compared traditional diffuser. comfort evaluated predicted percentage dissatisfaction ...

Abstract The use of computational fluid dynamics (CFD) to predict internal and external flows has risen dramatically in the past decade. This research aims commercial software, ANSYS Fluent V.14.5, illustrate effects rudder blade pitch on hydrodynamic performance marine propeller by experimenting with propellers rudders M/V Tan Cang Foundation ship, which designed conditions as follows: diamete...

Pitch regulation plays a significant role in improving power performance and achieving output control wind turbines. The present study focuses on novel, pitch-regulated vertical axis turbine (VAWT) with inclined pitch axes. effect of two parameters (the fold angle the incline angle) instantaneous aerodynamic forces overall straight-bladed VAWT under tip-speed ratio 4 is investigated using an ac...

Viscose rayon is a natural fabric from regenerated cellulose derived wood pulp, bamboo, or cotton linters. The viscose industry relies on electricity to generate steam for textile production. This study aims optimize the 45-ton-per-hour Atmospheric Fluidized Bed Combustion (AFBC) boiler. Its efficiency 78.16%, lower than benchmark of 85.78%. Boiler decreases as flue gas temperature increases, r...
