Thermal Diffusivity of n-Dodecane from 290.15 to 633.15 K and Pressures to 5.0 MPa

Experimental thermal diffusivity measurements for n-dodecane, a key component of aviation kerosene. The data was collected by Zhao Lei using a dynamic light scattering method across a temperature range of 290.15 to 633.15 K and along seven isobars up to 5.0 MPa. The dataset includes a polynomial correlation for thermal diffusivity against temperature and pressure, with an absolute average relative deviation of 0.68% from experimental data.

Use Cases

• Calibrating computational fluid dynamics models for aviation fuel combustion based on thermal diffusivity data.
• Developing predictive correlations for thermophysical properties of hydrocarbon mixtures based on pure component data.
• Analyzing the behavior of n-dodecane near its critical point for supercritical fluid applications.
• Validating experimental measurement techniques for thermal diffusivity against the provided uncertainty estimates.

Strengths

• Covers a wide temperature range from 290.15 to 633.15 K, including near-critical conditions.
• Reports a relative combined uncertainty of 0.026 for the experimental system at a 95% confidence level.
• Provides data along seven distinct pressure isobars from 0.1 to 5.0 MPa.
• Includes a polynomial correlation with a reported average deviation of 0.68% from experimental data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data is specific to a single pure component (n-dodecane), limiting direct applicability to complex fuel blends.
