Dehydrogenation of cyclohenxanol to cyclohexanone
The dehydrogenation of cyclohexanol to cyclohexanone has been studied in detail. The thermodynamic equilibrium constants at various temperatures have been collected from literature and the equilibrium conversions have been ... -
Studies on the catalytic hydrogenation of salicyloyl chloride
In the present work, catalytic hydrogenation of salicyloyl chloride to salicylaldehyde by Rosenmund reduction using Pd-C catalysts was extensively studied. A stirred slurry reactor was used for studying this reaction. The ... -
Modeling of phase inversion phenomenon
Turbulent liquid–liquid dispersions are frequently encountered in the chemical industry in various operations such as liquid–liquid extraction, liquid–liquid reactions, polymerization, and direct contact heat transfer. ... -
Studies in hydrodynamic and electrohydrodynamic instabilities of fluid-solid and fluid- fluid interfaces
The study of hydrodynamic and electrohydrodynamic stability is an important branch of fluid mechanics and has applications in various areas of chemical engineering and biophysics. The detailed study of hydrodynamic stability ... -
Polymerization in supercritical fluids
The chemical industry has become increasingly aware of environmental concerns over the use of volatile and hazardous organic solvents to synthesize commercial polymers. Attractive properties of supercritical fluids make ... -
Oxidation of alkyl aromatics Part II : oxidation of toluene to benzoic acid in presence of promoters
The investigation on the catalytic vapour-phase oxidation of toluene in the presence of gaseous promoters was taken up to determine the operating conditions favourable for the maximum conversion to benzoic acid. The effects ... -
A syntactic model for representing the behaviour of mechanical artefacts in product models
Product models are being proposed as information models to drive the entire product lifecycle. CAD models that drive the product development cycle presently are primarily a repository of shape information and, therefore, ... -
Fracture Processes in Sustainable Fibrous Cementitious Composites: Insights from Statistical Mechanics and Natural Time Analysis
In recent years, there has been a growing demand in the construction industry for slender, durable, and high performance structural elements. This has led to the development of an advanced cementitious composite material ... -
Understanding Strain Rate Response of Geomaterials through Orthogonal Cutting Experiments
Cutting is a complex, large deformation process used for the removal of material during various engineering operations. In geomaterials, such as soils and rocks, the mechanism of cutting is encountered during operations ... -
Passive Interfacial Evaporation-based Thermal Desalination Systems
Desalination offers a promising solution to the global water shortage by utilizing the vast resource of seawater. With 26% of the world’s population lacking access to potable water currently, there is a growing need to ... -
some studies on the mean Meriodional circulation droughts
It has been observed that during a break in the Indian southwest monsoon, the middle latitude circulation enters low index regime or Rossby regime. These Rossby waves are found to propagate southwards even up to Indian ... -
Structure of shock waves in a partially ionized gas. Ph.D. Thesis
A unified picture of the structure of steady one-dimensional shock waves in a partially ionized gas in the absence of externally applied electric or magnetic field is presented. The investigation is based on a two-temperature, ... -
From Sanitation to Soil: Evaluating Faecal Sludge-Based Amendments for Nutrient Circularity and Sustainable Agriculture
Globally, especially across developing regions, cities face a dual challenge: managing faecal sludge (FS) from on-site sanitation systems in a safe and sustainable manner, while simultaneously restoring soils degraded by ... -
Electrohydrodynamics of a Viscoelastic Drop
The behavior of a drop in electric fields is critical for diverse natural and industrial applications, including inkjet printing and electrohydrodynamic atomization. This complex phenomenon is governed by the balance of ... -
Assessing the state of the glaciers in the Parvati basin of the Himalaya under a changing climate
The Himalayan cryosphere is one of the most climate-sensitive components of the Earth's system, acting as a critical water tower for millions of people across South Asia. Snow and glacier melt from this region contribute ... -
