Finite Element Simulation Analysis of Concrete Arch dams: A Review

By A. Mishra

Abstract: The loads on the arch dam and the physical properties of materials of the dam and the bedrock are undefined, and can be designated with random variable. Due to the huge volume, the complex structure of the dam and excessive random variable, the static analysis of the dam is tough. The dam is a higher order statically unspecified structure, and the variation of the temperature obviously marks the stress and …

Rising Temperatures and Surface Mass Loss in Greenland: Implications for Regional Glacier Dynamics and Global Sea Level Rise

By Disha Manish Deshpande, Ajaykumar R. Kambekar

Abstract: In Greenland, the ice sheet serves as one of the strongest indicators of global climate change, with consistently rising temperatures driving it toward an even more negative mass balance. Over the last two decades, warmer conditions have exacerbated surface melting, darkened ice, and resulted in feedback stimulating further loss. This study assesses how those temperature trends—particularly during summer peak months—have impacted the stability of Greenland's ice, and then, more importantly, …

Numerical Investigation of Influence of Rate of Rotation on Formation of Vapor Around Two Heated Circular Cylinders Immersed in Water Inside a Channel

By Ravi Pullepudi, S. K. Maharana

Abstract: AbstractThe complexity problem of fluid flow and heat transfer over an array of circular cylinders are common in industrial applications of the fluid dynamics. The complex nature of the problem encountered in industry, gives rise to certain significant dimensions in the fluid dynamics theory. Some of them are the fluid flow interaction, interferences in flow and vortex dynamics which are typically found in compact heat exchangers, cooling of electronic equipment, …

Grid Sensitivity and Its Impact on the Hydrodynamics of a Submerged Vessel

By Sahul Muhique, Kalyan Kalita, Kalyan Das

Abstract: Accurate prediction of hydrodynamic characteristics is essential for the design and performance assessment of underwater vehicles and offshore structures. Computational fluid dynamics (CFD) has emerged as an effective tool for analyzing fluid flow behavior around submerged bodies, enabling detailed evaluation of pressure distribution, drag forces, and flow patterns. In this study, the effect of mesh refinement on the hydrodynamic analysis of a DRDC-STR submarine nose section was investigated using ANSYS …

Cargo Containers Pilferage: Tracking and Checking

By Devanshu Suman, Ashutosh Kumar

Abstract: Due to pilferage from the cargo containers, industries suffer a loss of huge sum of money as the cargo containers are used in transporting vast amount of manufactured product/raw shipment material from one place to another. During the transportation, once the pilferage or employee theft is done, all the authorities intricate whether guilty or not comes under the point of suspicion. This results in culminate loss of the industry and …

Start-Up of the Two-Stage UASB Reactor Using Paper Mill Effluent

By Hazrat Shahab, Alia Naz, Arshad Ali

Abstract: This study is designed to evaluate the treatability potential of using two-stage anaerobic reactors (R-I and R-II) for the treatment of paper mill effluent. It was observed that the bicarbonate alkalinity of the reactors increased from 215 to 266 mg-CaCO3/L in reactor R-I and from 456 to 604 mg-CaCO3/L in reactor R-II, by the addition of an external buffer solution. The average volatile fatty acids formation noticed within the reactors …

Nonlinear Three Dimensional Dynamic Analysis of Titanium Drilling Riser

By Rizwan A. Khan, Abhishek Khandelwal, Suhail Ahmad

Abstract: Titanium alloys are selected for a high-pressure drilling riser’s application due to its high specific strength, corrosion resistance, and favorable elastic properties. The qualification of this titanium alloy requires assessing its resistance to hydrogen embrittlement and stress corrosion cracking due to seawater with/without cathodic protection, evaluating its dynamic response under long crested random sea. The response analysis is based on a simulation technique which duly considers the various nonlinear effects …

Status of Surfactant-Polymer Flooding

By James J. Sheng

Abstract: Abstract Surfactant-polymer (SP) flooding emerged from the principle that good sweep efficiency and displacement efficiency result in good oil recovery. Its research and development was shifted to alkaline-surfactant-polymer (ASP) because higher oil recovery can be achieved from the latter. Apparently, some research-development focus is coming back to SP, because ASP has problems in practical applications, e.g., scaling and emulsion. This paper provides the status of surfactant-polymer flooding technology. It covers …
