CFD simulation & consultancy

CFD analysis built around the engineering decision

High-fidelity flow, heat-transfer, reacting-flow and multiphase analysis for aerospace, defence, propulsion, energy and process systems—from a precisely defined question to traceable results and a practical design recommendation.

A complete analysis service

More than a simulation run

LIKUA takes responsibility for the complete numerical-analysis chain: the physical question, model selection, geometry and mesh strategy, boundary conditions, solver configuration, convergence assessment, sensitivity checks, interpretation and reporting.

The work is performed by engineers who develop compressible-flow and multiphysics software and use it in real design workflows. This allows the numerical method to be adapted to the problem when a standard black-box workflow is not sufficient.

Core application areas

Analysis for demanding flow environments

Scope is selected according to the physical question. A project can cover a single component, a coupled internal-flow system or a complete design study across an operating envelope.

01

External aerodynamics

Subsonic, transonic, supersonic and hypersonic flow around vehicles, projectiles, aircraft components and high-speed configurations.

  • Drag, lift, moments and surface loads
  • Shock systems and wave interaction
  • Separation and boundary-layer behaviour
  • Aerothermal surface environments
02

Rocket and propulsion flows

Internal and external flow analysis for rocket motors, nozzles, plumes and aero-propulsive systems.

  • Chamber, nozzle and exhaust-flow performance
  • Nozzle losses, side loads and transient start-up
  • Plume expansion and plume–body interaction
  • Base bleed and rocket-assisted concepts
03

Ramjet, ducted rocket and intakes

Coupled assessment of high-speed air intakes, internal flow paths, combustor entry conditions and propulsion–airframe interaction.

  • Intake starting and operating range
  • Pressure recovery and flow distortion
  • Shock–boundary-layer interaction
  • Inlet, duct and combustor matching
04

Combustion and reacting flow

High-temperature internal-flow studies where chemistry, heat release and mixing determine performance and thermal loading.

  • Reactant mixing and residence time
  • Combustion environments and hot-gas paths
  • Thermochemical boundary-state definition
  • Solid-fuel and particle-fuel applications
05

Particle-laden and multiphase flow

Eulerian analysis of dispersed phases in compressible and industrial flows, including momentum and heat exchange with the carrier phase.

  • Particle transport and size-dependent behaviour
  • Drag, heating and interphase exchange
  • Boron-containing fuel environments
  • Process equipment and separation systems
06

Thermal, ablation and conjugate problems

Coupled flow-and-thermal assessment for hot structures, thermal protection and material-response boundary conditions.

  • Convective heat flux and wall temperature
  • Conjugate heat transfer
  • Pyrolysis, charring and regression-rate assessment
  • Steady and transient thermal exposure
Industrial and energy applications

Compressible and incompressible engineering flows

The same verification-led approach is applied beyond aerospace: hydrodynamics, hydro-power, pumps, turbomachinery and process-engineering equipment where pressure loss, flow distribution, cavitation risk, mixing or phase transport drives performance.

Hydrodynamics Internal water flows, free-stream loading and hydraulic performance.
Pumps & turbomachinery Pressure rise, efficiency, recirculation, separation and operating maps.
Process equipment Flow distribution, mixing, pressure loss and geometry optimisation.
Multiphase systems Dispersed-phase transport, flotation-related flows and phase interaction.
Methods selected for the case

Physics and numerics matched to the operating regime

Flow regimes

  • Low-speed to hypersonic compressible flow
  • Steady and time-accurate simulation
  • Laminar and turbulent flow
  • Internal, external and coupled flow paths

Physical models

  • RANS and scale-resolving turbulence options
  • Heat transfer and conjugate thermal coupling
  • Reacting and particle-laden flow
  • Material-response wall models

Computational approach

  • Parallel 2D, axisymmetric and 3D analyses
  • Structured, unstructured and polyhedral meshes
  • Local refinement around shocks, walls and interfaces
  • HPC execution for design sweeps and large cases
Credibility

Verification and validation are part of the work

A visually plausible result is not enough. The evidence required depends on the decision and may include conservation checks, residual and monitor histories, mesh sensitivity, time-step sensitivity, comparison with analytical limits, benchmark cases, test data or an independent reference method.

Numerical verification

  • Domain and boundary-condition review
  • Mesh-quality and near-wall-resolution assessment
  • Convergence of residuals and engineering monitors
  • Mass, momentum and energy balance checks
  • Mesh, time-step or model sensitivity where required

Physical validation

  • Comparison with experimental or flight/test evidence
  • Benchmark and literature-case reproduction
  • Correlation of pressures, forces, heat loads and performance
  • Clear separation of validated findings and engineering inference
  • Documented uncertainty, limitations and applicability
Workflow

A disciplined path from question to recommendation

Define Decision, geometry, operating envelope, known data and success criteria.
Model Physical assumptions, boundary conditions, fidelity and mesh strategy.
Compute Robust solution, monitored quantities and controlled numerical settings.
Verify Convergence, balances, sensitivity and comparison with available evidence.
Decide Engineering interpretation, trade-offs, limitations and next design action.
Engagement formats

From one critical case to an iterative design programme

Focused analysis

A fixed-scope calculation answering one clearly bounded engineering question.

Design comparison

Several geometries or operating points compared using consistent metrics.

Independent review

Audit of an existing CFD model, result set, methodology or technical claim.

Validation support

Simulation planning around test data, instrumentation and correlation objectives.

Embedded engineering

Ongoing CFD support integrated into a customer design and review cycle.

Custom model development

Problem-specific physics, solver functionality or workflow automation.

Start with the engineering question—not a predefined simulation package.

Send the geometry, operating conditions, available test data and the decision the analysis must support. LIKUA will define a proportionate technical scope and the evidence required for a defensible answer.
