Fluid-Structure Interaction Simulation of Parachute by Eulerian-Lagrangian penalty method
Abstract: In general, modeling and simulation of a model consisting of fluid and solid combinations has been considered difficult, and it has become impossible in terms of computer dependencies and accuracy to be analyzed by Fluent or other programs. The parachute evaluation process, which is historically based on a large amount of experimental data, necessitates many falling experiments. These tests can be costly and time-consuming, and they don't always allow for …

Fluid-Structure Interaction Analysis of a Rubber Bellow Segment made of Hyper Elastic Material
Abstract: Fluid-structure interaction (FSI) is the interaction of a moveable and/or deformable structure that is immersed in a fluid and/or contains a fluid. Motion of the structure causes a change in the fluid’s stresses that act on the structure’s wetted surface, which in turn causes a change in the structure’s motion. The present research analyses the deformation produced in a hyper elastic rubber bellow segment due to the pressure generated by …

Understanding Side-wind Dynamics and Deciphering Ringsail Parachute Drift
Abstract: The geometric complication caused by the "rings" and "sails" used to make the parachutist's canopy provides a considerable computationally problem, which is the focus of this paper's fluid–structure interaction (FSI) modeling of ringsail parachutes. Based on the sustained space-time FSI (SSTFSI) method, we have developed an FSI simulation of ringsail jumping devices. The FSI Geometric Smoothing Technique and the Homogenized Modeling of Geometric Porosity represent a pair of the above …

Investigation of Electric Spring for LVRT Capability Improvement of Fixed Speed Induction Generator based Wind Farm
Abstract: This paper investigates the ability of electric spring (ES) for the low voltage ride-through (LVRT) capability improvement of fixed speed induction generator (FSIG) based wind farm (WF). With increased renewable energy integration, new grid codes are declared by various power system grid operators in order to maintain system stability. LVRT capability is the prime and most difficult requirement of these new grid codes. FSIG based WFs are largely installed but …

Study on the Method of Prediction of Complete Inflation Time of Parachute
Abstract: In general, the parachute test is a long test period, expensive, and difficult to measure with accuracy, which makes it a very laborious and laborious task due to the strong nonlinearity of the fabric of the parachute. Therefore, attempts have been made to overcome this by using a parachute testbed or by simulation, but in our country, there is no numerical simulation of the parachute, and no research has been …

Comparative Study on Stabilization of Expansive Soil using Cement Kiln Dust and Ceramic Dust
Abstract: In India, expansive soils cover about 20% of total land area, these soils increase in volume (swell) during winter season and decrease in volume (shrink) during summer season. Due to this contradiction behaviour many civil engineering structures constructed on expansive soils get damaged severely, out of which pavement is the most because they are lightweight and extend over large areas. Stabilization of Expansive soil is of most importance, since to …

Investigation on Clay Soil Stabilization using Plastic Powder
Abstract: A huge amount of black cotton soil or clayey soil is available all around the world which leads to a waste of land for construction uses, since it has expansiveness, swelling and shrinkage properties etc. So we have tried to resolve this problem by stabilizing the black cotton soil by waste material marble powder. This study impact with the effect of PP (PP) on expansive soil by conducting the laboratory …

Performance-Based Fire Safety Assessment and Optimization of a Mixed-Use High-Rise Building Using NBC 2016, Hydraulic Adequacy, and Evacuation Time Analysis
Abstract: This paper presents a performance-based fire safety assessment of a simulated 92 m mixed-use high-rise building containing parking, commercial, office, and residential occupancies. Rather than relying only on prescriptive compliance, the study evaluates whether the installed fire protection strategy can maintain tenable conditions and deliver adequate suppression performance during a credible design fire. Using the base data supplied for the Metro Central Tower case, the work determines fire load density, …

RURAL ROAD PAVEMENT SUBGRADE AND SUBBASE IMPROVEMENT USING LIME, FLY ASH AND GEOSYNTHETICS IN SOUTH GUJARAT REGION
Abstract: South Gujarat region comprises of Narmada, Surat, Tapi, Navsari, Valsad and Dang districts. The majority of the region has soil type varying from clayey to clay loam type soil. Also, the average annual rainfall is more than 1500 mm in the region. Some parts of Surat, Navsari and Valsad districts are in coastal region and have soft and compressible clayey soil. Under this environmental scenario of soil, climate and increasing …
