Fuel Properties for DF#2

Fuel Properties for DF#2

Fuel Properties for DF#2

(OP)
Does anyone know where I can get fuel properties for diesel fuel number 2?

I'm trying to model a valve in Floworks and need the density, dynamic viscosity, specific heat (Cp), and thermal conductivity.

Thanks,
Dummi  

RE: Fuel Properties for DF#2

Diesel 2
A general-purpose, middle distillate fuel for use in diesel engines, especially in applications with relatively high loads and uniform speeds.

SG = .813
API = 42.4
Flash = 58.3 ºC
Cloud Point = -47ºC
Pour Point = -51ºC
cSt = 1.9 min to 4.1 max @ 40ºC

RE: Fuel Properties for DF#2


Thermophysical properties may vary a bit with chemical composition and distillation range. The thermal conductivity, k, and the specific heat, σ, are both affected by temperature and polarity of the molecules.

You may add to the list brought by BigInch, a thermal conductivity, k, of about 0.14 W/(m.K).

This item can be roughly estimated using an empirical formula such as:

k = 0.1172(1-0.00054 t)/ρ

where t is in oC, and ρ is the density at 15oC in kg/L.

The specific heat σ at ambient conditions would be about 1.8 kJ/(kg.K).

As an example, Stachowiak and Batchelor (Engineering Tribology, Elsevier) suggest, as a rough approximation for lubes:

σ = (1.63 + 0,0034 t)/s2

where s is the specific gravity at 15.6oC
