Scientific evidence · Engineering interpretation · Decision value

Selected Work and Engineering Case Studies

A focused selection of public and non-confidential work showing how scientific concepts, modelling tools, reproducible calculations and engineering frameworks can support process diagnosis, validation planning, technology assessment, process development and scale-up decisions.

How to read this page

Each case is presented according to its evidence maturity and decision relevance

The purpose is not to display every archived file or historical calculation. Selected materials are reconstructed, documented and interpreted according to technical integrity, ownership, validation status, transferability and usefulness for scientific or engineering decisions.

Evidence maturity

Diagnostic frameworks, tested screening tools, research reconstructions and scientific hypotheses are labelled separately.

Decision relevance

Each case identifies the technical question, the contribution and the decision or development activity it can support.

Rights and confidentiality

Authorship, ownership, licensing, employer rights and confidentiality are reviewed before material is published.

Transferability limits

Public examples demonstrate methods and reasoning; they do not replace representative validation or site-specific engineering.

Current public case studies

Examples across reaction engineering, water treatment, thermochemical conversion and combustion science

The cases have different maturity levels and provide different forms of value. Their status labels are part of the technical interpretation and are not interchangeable validation claims.

Reaction engineering · Fuels and gas processing

Desulfurization Reaction–Transport Regimes

A structured framework for distinguishing intrinsic chemistry from mass-transfer, diffusion, adsorption, hydrodynamic and downstream-separation limitations in sulfur-removal systems.

Engineering diagnostic framework

Technical question

Which mechanism actually controls process performance, and does a proposed intensification method address that bottleneck?

Contribution

  • Reaction–transport regime classification
  • Bottleneck-oriented interpretation
  • Energy-normalized intensification perspective
  • Validation and scale-up questions

Decision value

Supports experimental design, process comparison, claims assessment and selection of chemical, transport, separation or equipment interventions.

Wastewater treatment · Advanced oxidation

AOP Kinetic Process Framework

A Python framework for interpreting hydroxyl-radical competition, water-matrix scavenging, apparent kinetics, treatment time and selected process-level indicators.

Tested screening framework

Technical question

How strongly do background water constituents compete for radicals, and what does that imply for apparent pollutant removal?

Contribution

  • Matrix-scavenging calculations
  • Radical-utilization fractions
  • Apparent kinetic and treatment-time estimates
  • Carbonate and alkalinity utilities
  • Automated software tests

Decision value

Supports matrix characterization, scenario comparison, interpretation of apparent AOP performance and preparation of laboratory or pilot validation programmes.

Biomass · Biochar · Thermochemical conversion

Biochar and Biomass Process Modeling

A reconstruction-oriented repository containing a simplified Cantera-based biomass-conversion mechanism, curated simulation cases and explicit model-consistency and validation guidance.

Research reconstruction

Technical question

Which qualitative trends in archived simulations remain useful, and what must be resolved before the model can support design or scale-up?

Contribution

  • Cantera-compatible mechanism and examples
  • Curated moisture, temperature and atmosphere cases
  • Explicit temperature-unit warning
  • Model-consistency and validation plan
  • Responsible carbon-management boundaries

Decision value

Demonstrates how legacy scientific material can become a transparent, auditable development foundation before model complexity or industrial claims are increased.

Combustion science · Nanoparticle inception

NDMS Persistence–Stabilization Closure

A scientific hypothesis and executable conceptual model examining whether transient precursor association, persistence and stabilization can bridge molecular chemistry and persistent particle inception.

Scientific hypothesis

Scientific question

How might reversible precursor association progress toward the first persistent particles without assuming a universal inception mechanism?

Contribution

  • Explicit association and dissociation terms
  • Non-stabilizing loss pathways
  • Bounded stabilization probability
  • Executable zero-dimensional demonstration
  • Testable validation questions

Scientific value

Provides a structured and falsifiable basis for comparing persistence and stabilization pathways while keeping the hypothesis separate from established mechanisms.

Controlled development programme

Kinetic Intelligence: mechanism analysis and adaptive chemistry

Historical mechanism-analysis, reaction-network, reduction and adaptive-chemistry methods are being re-derived and rebuilt as a modern Python and Cantera framework.

The programme remains under controlled reconstruction and benchmark validation. It is not presented as a validated public software product.

Public release will follow only after reactor-restart controls, conservative state transfer, mechanism switching and selected methane benchmarks have been executed, documented and reviewed reproducibly.

Planned technical modules

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

Practical engineering use

How the demonstrated methods can support real decisions

Public frameworks are not substitutes for confidential, site-specific engineering. They demonstrate reasoning methods, technical questions and quality controls that can be adapted to suitable projects.

Bottleneck diagnosis

Separate reaction, transport, hydrodynamic, separation and operating constraints before selecting an intervention.

Model selection

Determine whether screening calculations, detailed kinetics, reactor simulation or CFD are justified by the decision and available evidence.

Validation planning

Define measurements, controls, representative conditions and acceptance criteria required to test a technical claim.

Technology assessment

Test whether a proposed technology addresses the governing mechanism and creates net value after energy, chemicals, reliability and downstream burdens.

Scale-up risk

Identify changes in residence time, mixing, heat transfer, transport, operability, materials and control that may prevent laboratory performance from transferring.

Technical communication

Translate complex findings into explicit assumptions, evidence boundaries, decision criteria and development actions.

Role within the professional ecosystem

Public evidence here; defined professional engagement through appropriate channels

This website documents selected methods, publications, reproducible resources and non-confidential case-study reasoning. It is the scientific and engineering evidence layer of the wider professional ecosystem.

A separate client-facing consulting platform may later present defined services, deliverables and engagement models without duplicating the technical resources published here.

Confidential project information, employer-owned material, proprietary operating data and unverified claims are not used as public marketing content. Relevant leadership, specialist, advisory and collaborative discussions can be initiated through the Professional Engagement section.
