Control of a fluid velocity profile by injection and suction of non-ionized flow in presence of a uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible and viscous conducting fluid flow has been investigated in a circular channel. The channel wall has been assumed to be non-conducting and porous. It has been subjected to a uniform steady ...

With the growing stress on today’s power systems, many utilities are increasingly and there is a need for inclusion of security analysis capabilities in the energy management systems. Transient Stability analysis is the evaluation of the ability of the power system to withstand to a set of severe but credible contingencies and to survive transition to an acceptable steady state condition. The p...

Microbursts have been simulated and studied using different physical and numerical modeling methods. In the present study, the steady impinging jet model was comprehensively studied by using a 2-footdiameter (0.61 m) microburst simulator available in the Department of Aerospace Engineering at Iowa State University. Point measurements and Particle Image Velocimetry (PIV) results revealed a detai...

Computational modeling is an important tool to understand and stabilize transient turbulent fluid flow in the continuous casting of steel to minimize defects. The current work combines the predictions of two steady Reynolds-averaged Navier–Stokes (RANS) models, a ‘‘filtered’’ unsteady RANS model, and two large eddy simulation (LES) models with ultrasonic Doppler velocimetry (UDV) measurements i...

[1] We have conducted double‐shear biaxial deformation experiments in layers of NaCl within its fully‐plastic (FP) regime up to large shear strains (g < 50) with velocity steps. From this, we have empirically formulated a rate‐ and state‐dependent flow law which explains the transient mechanical behavior. The steady state flow stress in the FP regime can be explained by a power‐law with a stres...

Deep reinforcement learning approaches are becoming appealing for the design of nonlinear controllers voltage control problems, but lack stability guarantees hinders their deployment in real-world scenarios. This paper constructs a decentralized RL-based controller inverter-based real-time distribution systems. It features two components: transient policy and steady-state performance optimizer....

FOllin is an excellent fluid for achieving mobility control of gas in porous media. Practical application of fOllins for EOR processes, however requires a predictive model of foam displacement. Further, quantitative information on fOllin-flow behavior at reservoir flow rates llild pressures is required as input to llily field-scale modeling. An experimental and mechanistic-modeling study is rep...
