User Pressure Data refers to any experimental or externally calculated pressure‑versus‑crank‑angle curve that you import into AVL Boost instead of relying solely on the software’s default combustion models (e.g., Vibe, Wiebe). UPD is particularly valuable when:
), and liquid fuel properties if direct injection (DI) is simulated. Example (Iso-Octane / Gasoline): Example (Diesel): 3. Element-by-Element Component Configuration
Define ambient temperature, pressure, and air composition.
To enable UPD:
Best for predictive/diagnostic performance matching. It defines the mass fraction of fuel burned ( ) as a function of crank angle:
AVL Boost is a 1D thermodynamic simulation tool that models the entire engine as a network of interconnected components: cylinders, pipes, plenums, air filters, turbochargers, intercoolers, catalytic converters, and more. Each component is defined by its physical geometry and operating parameters, and the software solves the governing equations of gas dynamics, heat transfer, and combustion.
