RESEARCH PROJECTS

Investigation of Recent C3S Hydration Inferences using a Multi-constrained Multi-ionic Single

Particle Modeling Strategy

Developed an advanced continuum-based multi-physical fully time-resolved model to

illustrate the concurrent progression of reactant (non -porous solid) dissolution and product

(porous solid) precipitation for processes involving nucleation and growth.

Formulated a multi-constrained multi-ionic continuum-based single particle model by

rigorous multi-ionic transport, non-linear equilibrium kinetics, and particle ensemble features

of nucleation and growth such as neighboring particle proximities and space filling effects.

Two-Phase Flow: Buoyancy Driven Flow of a Partially Miscible Droplet at Low Reynolds Number

Studied low Reynolds number flow past a solid/liquid sphere both analytically and

computationally.

Computationally simulated the buoyancy driven flow of a partially miscible droplet using the

level set methodology with COMSOL and observed flow and droplet dynamics.

Analyzed and redefined different droplet shapes depending up on various dimensionless

parameters describing different flow regimes.

INDUSTRIAL PROJECT

Solvent Recovery System for Methanol and Water

Simulated chemical process using HYSYS and ASPEN PLUS.

Involved in PFD’s and P&ID’s, equipment selection, sizing of tanks, vessels, pumps, and

exchangers.

Prepared valve, line, and instrumentation lists and performed cost analysis.

Developed material and energy balance spreadsheets to review daily production status.

ACADEMIC PROJECTS

Process Simulation Models: Propylene Glycol Production from Propylene Oxide, Styrene Production

from Ethyl benzene

Developed steady state simulation models – Propylene glycol production from propylene

oxide using HYSYS, Styrene production from ethyl benzene using Aspen Plus.

Optimized the process for the given design specifications.

Cyclohexane Conformational Studies and Thermochemistry Calculations in Gaussian

Studied conformational variations and their relative energies during the inversion of

cyclohexane with HF, MP2, and mPW1PW91 and with basis sets 6-31G(d,p), 6-31+G(d,p).

Explored thermochemistry calculations by evaluating quantities such as enthalpy, Gibbs free

energy, and the heat of reaction for hydrogenation of benzene, cyclohexene to cyclohexane.

Computational Modeling of a Parallel Plate Electrochemical Reactor (PPER)

Computationally studied a parallel plate electrochemical reactor (PPER) where the reduction

of hexavalent chromium Cr (VI) to trivalent chromium Cr (III) takes place via a homogenous

reaction between Cr (VI) and Fe (II) in a solution.

Investigated the effects of different dimensionless parameters such as space velocity of feed

solution, electrolyte concentration, distance between the electrodes, and cell potential on

conversion of Cr (VI) to Cr (III).

Computational Modeling of a Laminar Flow in a Z-shaped Close-coupled Fitting

Modeled the laminar flow behavior and its structure inside a duct system having a z-shaped

close-coupled fitting.

Estimated the pressure loss coefficients from dual pipe elbows which are arranged in a z-

shaped configuration with several distances apart from each other.

Derived the correlation between the pressure loss and the separation distance between

elbows.
