Service overview

Make the mechanisms behind fluid system performance visible, measurable and actionable.

Computational fluid dynamics for internal and external flows, cooling, pressure loss, mixing, rotating machinery and aerodynamics, connected directly to product and system design decisions.

Service model
Use focused specialist support for a defined gap, or assemble a multidisciplinary team around a complete workstream. The structure follows the interfaces and decisions in the scope.
Delivery
Choose a project, dedicated team, hybrid engagement or managed service. Milestones, client responsibilities and acceptance criteria are agreed before execution.
Control
Scope, assumptions, evidence, ownership and review rhythm remain visible. Changes and unresolved risks are recorded with an accountable decision owner.

Delivery model

How we deliver.

Engineering work begins with the decision that must be supported and the evidence required to make it responsibly. Requirements, interfaces, assumptions and validation authority stay visible throughout delivery.

01

Inputs we establish

Product requirements, operating conditions, geometry, interfaces, existing test evidence, standards and release constraints.

Missing or uncertain inputs are recorded with an owner and their effect on model or design authority.
02

How the team works

An accountable engineering lead coordinates the mechanical, simulation, electronics, embedded or digital specialists required.

Client technical owners remain connected through design reviews, issue decisions and agreed approval gates.
03

How work is controlled

Models, calculations, software, drawings, assumptions, interfaces and changes are reviewed at defined maturity points.

Each output states its purpose, limitations, validation status and the next decision it is intended to support.
04

How success is measured

Requirement coverage, technical risk retirement, interface closure, evidence quality and readiness for the next lifecycle stage.

Progress is reported through accepted engineering outputs and resolved decisions, not activity volume alone.

Solutions

Solutions for common delivery needs.

The starting point can be a technical problem, a capacity gap or the need for a complete delivery workstream. CX24 first clarifies the current state, desired outcome and decision ownership.

01

Pressure loss or cooling performance is limiting the product.

How CX24 respondsOperating points, outputs and success criteria. The scope, responsible owners and evidence needed for closure are agreed before execution begins.
02

Aerodynamic behaviour needs improvement before a physical prototype.

How CX24 respondsFluid domain, mesh and physics setup. The scope, responsible owners and evidence needed for closure are agreed before execution begins.
03

Flow distribution or mixing is difficult to measure directly.

How CX24 respondsResidual, balance and solution behaviour monitoring. The scope, responsible owners and evidence needed for closure are agreed before execution begins.
04

Several geometry concepts must be compared consistently.

How CX24 respondsSensitivity and comparison with known behaviour. The scope, responsible owners and evidence needed for closure are agreed before execution begins.

Delivery approach

A clear path from scope to evidence.

The exact gates change by service, but ownership, review and measurable outputs stay explicit. Each stage establishes the information needed to enter the next one responsibly.

01

Scope

Operating points, outputs and success criteria.

Stage outcomeSimulation definition is prepared or updated before the work advances.
02

Prepare

Fluid domain, mesh and physics setup.

Stage outcomeFlow diagnostics is prepared or updated before the work advances.
03

Run

Residual, balance and solution behaviour monitoring.

Stage outcomeVerification checks is prepared or updated before the work advances.
04

Verify

Sensitivity and comparison with known behaviour.

Stage outcomeDesign comparison is prepared or updated before the work advances.
05

Improve

Design recommendation and validation priorities.

Stage outcomeAgreed next stage evidence is prepared or updated before the work advances.

What you receive

Typical deliverables.

Deliverables are adapted to the client environment and agreed acceptance criteria. The aim is to leave behind usable engineering, technology or operating capability, not presentation material alone.

01

Simulation definition

Domain, mesh, models and boundary conditions.

Assumptions, ownership, dependencies and the agreed review status are recorded with the output.
02

Flow diagnostics

Velocity, pressure, temperature and force measures.

Working files, source information and revision status are organised so the client team can continue using them.
03

Verification checks

Residual, balance, mesh and sensitivity evidence.

Results include the relevant checks, open issues, limitations and approval evidence, not only the final conclusion.
04

Design comparison

Alternatives, limitations and recommended changes.

Final handover identifies accepted scope, residual risk, next actions and the accountable owner for each action.

Proof Points

Evidence clients can review before acceptance.

Proof is defined through the engagement itself: accepted outputs, a visible decision trail, agreed measures and a usable handover.

01

Accepted outputs

Deliverables are mapped to agreed criteria, version status, accountable owners and review decisions.

02

Decision trail

Inputs, assumptions, interfaces, changes, exceptions and approvals remain connected to the work.

03

Delivery measures

Progress, quality, risk, backlog or service measures are selected for the actual engagement.

04

Usable continuity

Working files, source information, runbooks and handover actions leave the client able to continue.

Client names, project details and outcome claims are published only with permission. Evidence for a specific engagement is confirmed through the agreed scope, reviews and acceptance records.

Engagement Models

Choose a delivery structure that fits the responsibility.

Team shape, governance, commercial structure and acceptance are matched to the outcome CX24 is asked to deliver.

01

Defined project

Bounded scope, milestones, deliverables and acceptance criteria for a specific outcome.

02

Dedicated team

Stable specialist capacity integrated with client leadership, standards and delivery rhythms.

03

Delivery centre

Multidisciplinary capacity with named governance, shared methods and transparent reporting.

04

Managed service

Recurring responsibility operated against controls, service levels and improvement measures.
