# EVOLV Process Hydraulics Mass Balance
|
|
|
|
## Mission
|
|
Preserve physically coherent hydraulics and conservation behavior across interacting EVOLV process nodes.
|
|
|
|
## Harness Execution Contract
|
|
- Build a flow and accumulation map from current node contracts.
|
|
- Define invariants before edits:
|
|
- no unplanned conservation breaks
|
|
- split/merge behavior remains deterministic
|
|
- retention/transport assumptions are explicit
|
|
- Validate with scenario-based balance checks.
|
|
|
|
## Scope
|
|
- `nodes/reactor/`
|
|
- `nodes/settler/`
|
|
- `nodes/pumpingStation/`
|
|
- `nodes/valve/`, `nodes/valveGroupControl/`
|
|
|
|
## Workflow
|
|
1. Identify control volumes and interfaces.
|
|
2. Map inflow/outflow/storage terms and units.
|
|
3. Validate steady-state and transient behavior under typical scenarios.
|
|
4. Check edge cases: zero flow, reverse flow, surge, overflow.
|
|
5. Confirm output contracts preserve balance observability.
|
|
|
|
## Standards
|
|
- Keep units and sign conventions explicit.
|
|
- Avoid hidden source/sink terms.
|
|
- Document retention-time and mixing assumptions.
|
|
- Preserve existing contracts unless migration is defined.
|
|
|
|
## Test Expectations
|
|
Cover:
|
|
- mass/volume conservation under nominal operation
|
|
- split/merge and bypass edge cases
|
|
- boundary condition behavior at zero/low/high flow
|
|
- numeric stability under long-run ticks
|
|
|
|
## Deliverables
|
|
Return:
|
|
- balance model and assumptions
|
|
- changed files/tests with scenario evidence
|
|
- unresolved hydraulic risks and required field checks
|
|
|
|
Decision interview triggers:
|
|
- changes to balance assumptions affecting KPI/compliance outputs
|
|
- compatibility-breaking payload/topic changes for flow/volume data
|
|
- startup behavior changes with overflow/dry-run implications
