Research Methods, Modelling and Reproducible Engineering Tools

Selected methods, computational environments and public technical resources connecting applied physical chemistry, chemical kinetics, reactor modelling, CFD, thermochemical conversion, process development, experimental validation, pilot systems and industrial decision support.

How to use this page

One technical foundation serving different levels of decision

The same scientific resource can have different value for a researcher, engineer, manager or student. The purpose is therefore to present methods with enough technical depth for specialists while keeping their assumptions, maturity and practical relevance understandable to broader audiences.

Researchers

Examine assumptions, governing mechanisms, equations, reproducibility, validation boundaries and open scientific questions.

Engineers

Connect chemistry and transport phenomena to reactor behaviour, equipment performance, pilot configuration and scale-up risk.

Managers and technical leaders

Identify which evidence is decision-ready, which uncertainties remain and what development work is justified next.

Students and non-specialists

Follow the progression from a technical question through modelling and validation to a defensible practical conclusion.

Research and engineering themes

From molecular mechanisms to process and technology decisions

The work connects physical and chemical phenomena across molecular, reactor, equipment and process scales. The objective is not maximum model complexity, but the level of scientific detail required to answer the decision reliably.

Fit-for-purpose modelling

The appropriate model depends on the decision, not on complexity alone

A reliable development programme often moves through several modelling levels. Increasing detail is justified only when it resolves a material uncertainty, changes a decision or provides evidence that cannot be obtained more simply.

Level 1

Balances and screening calculations

Establish orders of magnitude, thermodynamic limits, material and energy balances, plausible operating windows and immediate feasibility constraints.

Level 2

Kinetic and mechanistic models

Resolve reaction pathways, controlling species, time scales, sensitivities, competing chemistry and intrinsic conversion behaviour.

Level 3

Reactor and CFD models

Couple chemistry with residence time, mixing, transport, heat transfer, phase behaviour and equipment-scale flow structures.

Level 4

Pilot and scale-up interpretation

Test representative operation, validate model assumptions and address operability, control, materials, safety, reliability and industrial transfer.

Public technical repositories

Reproducible resources with explicit maturity boundaries

The repositories below serve different purposes. Tested screening calculations, engineering diagnostic frameworks, reconstructed research models and scientific hypotheses are not presented as equivalent forms of evidence.

Reaction engineering · Desulfurization Engineering diagnostic framework

Desulfurization Reaction–Transport Regimes

A structured framework for distinguishing kinetic, mass-transfer, diffusion, adsorption, hydrodynamic and downstream-separation limitations in sulfur-removal processes.

Combustion · Nanoparticle inception Scientific hypothesis

NDMS Nanoparticle Inception

An executable conceptual closure investigating the competition between reversible precursor association, dissociation, non-stabilizing loss and particle stabilization.

Development workflow

A structured path from technical question to implementation

The workflow connects scientific formulation with evidence, engineering interpretation and practical implementation rather than treating modelling as an isolated activity.

1. Define

Establish the system, feed, products, constraints, uncertainties and decision objective.

2. Formulate

Identify the governing chemistry, transport, thermodynamics and process interactions.

3. Model

Select a transparent screening model, detailed kinetics, reactor simulation or CFD according to the decision need.

4. Validate

Compare with measurements, literature, benchmarks, balances and predefined acceptance criteria.

5. Translate

Connect the evidence to pilot configuration, scale-up, risk, operability and industrial decisions.

Controlled research-development programme

Kinetic Intelligence

Historical work on reaction rates, sensitivity, chemical reaction networks, mechanism reduction and dynamic adaptive chemistry is being re-derived and reconstructed as a modern Python and Cantera framework.

The internal package contains tested mathematical and software foundations. Full Cantera combustion benchmarks, real-mechanism state-transfer checks and reproducible performance evaluation remain required validation gates before public release.

Current maturity: research reconstruction. The framework is not presented as validated public software, an industrial predictive product or evidence of demonstrated computational speed-up.

Planned technical modules

  • Mechanism audit and provenance
  • Scenario and reactor-case management
  • Reaction-rate and flux analysis
  • Sensitivity and kinetic-control diagnostics
  • Chemical reaction-network analysis
  • Static and adaptive mechanism reduction
  • Conservative state projection
  • Validation and applicability reporting

Evidence, software and provenance policy

Public release follows technical and rights review

Archived materials are not uploaded automatically. Scientific value, software integrity, ownership, confidentiality and legal suitability are reviewed before public use.

Technical integrity

Equations, assumptions, units, balances, numerical methods and validation status are reviewed before results are described as reproducible, predictive or suitable for engineering use.

Authorship and licensing

Historical codes, mechanisms, figures and documents are screened for authorship, ownership, licence conditions and third-party reuse restrictions.

Confidentiality

Employer, client and project information is excluded unless it is already public, non-confidential, rights-cleared and appropriate for professional reuse.

This page presents scientific methods, modelling environments and public technical evidence. It supports the wider professional profile without converting unfinished research into marketing claims.

A separate client-facing consulting platform may later translate selected, rights-cleared and sufficiently validated capabilities into defined services, deliverables and engagement models without duplicating the technical resources published here.

Relevant scientific, engineering and professional discussions can be initiated through the Professional Engagement section.
