Disc formation in turbulent cloud cores: Circumventing the magnetic braking catastrophe
, 2012 We present collapse simulations of strongly magnetised, 100 M_sun, turbulent cloud cores. Around the protostars formed during the collapse Keplerian discs with typical sizes of up to 100 AU build up in contrast to previous simulations neglecting ...

Temperature and torque determination in brake drums
Sadhana, 1993 Simulation of temperature distribution in a brake drum and determination of drum brake torque has been carried out using finite element methods. The simulated temperature distribution and the brake torque determined were compared with observations carried out using an inertia dynamometer with a data-logging system.

Torque Enhancement for a New Magnetorheological Brake
Procedia Engineering, 2014 AbstractThe conventional magnetorheological fluid (MR) brake has been used as resistant sources for specific applications. However, the limited torque prevents it to be widely commercialized. This paper presents a new MR brake that improves the brake torque by enlarging the magnetic field strength.

Energy Science &Engineering, EarlyView.An adaptive fuzzy controller using an interval type‐3 fuzzy logic system replaces the SMC switching term to mitigate chattering while preserving global stability for islanded inverters. Simulations show lower THD, greater robustness to disturbances and parameter variations, and improved voltage‐tracking accuracy, with applicability to other uncertain ...
