CL_mod_aeroPanelCoefV

Aerodynamic coefficients for a flat plate (free molecular flow)

Calling Sequence

[res1, res2, ...] = CL_mod_aeroPanelCoefV(vel_wind, normal, temp, temp_p, m_mol_mass, ratio_spec, alpha, nsides, res)

Description

Parameters

vel_wind:

Wind velocity vector (velocity relative to the plate) [m/s]. (3xN or 3x1)

normal:

Normal vector to the flat plate defining the reference side. (3xN or 3x1)

temp:

Atmospheric temperature [K]. (1x1 or 1xN)

temp_p:

Temperature of the flat plate (wall) [K]. (1x1 or 1xN)

m_mol_mass:

Mean molar mass of incident flow molecules [kg/mol]. (1x1 or 1xN)

ratio_spec:

Ratio of number of molecules re-emitted specularly (between 0 and 1). (1x1 or 1xN)

alpha:

Accommodation coefficient. It must be between 0 and 1. (1x1 or 1xN)

nsides:

(integer) Number of sides to be considered: 1 or 2. (1x1 or 1xN)

res (string):

Names of computed quantities. (1xP)

res1, res2, ...:

Computed quantities. (1xN or 3xN)

Examples

// vel_wind = wind velocity vector relative to the plate
vel_wind = [-7000; 0; 0];
// ang = angle between normal and -vel_wind
ang = CL_deg2rad(0 : 180);
normal = [cos(ang); zeros(ang); sin(ang)];
temp = 1100; // K
temp_p = 300; // K
m_mol_mass = 0.015; // kg
ratio_spec = 0.1;
alpha = 1;

// Drag/lift coefficients - one side
[cx, cz] = CL_mod_aeroPanelCoefV(vel_wind,  normal, temp, temp_p, m_mol_mass, ratio_spec, alpha, 1, ["cx", "cz"]);

scf();
plot(CL_rad2deg(ang), cx, "r");
plot(CL_rad2deg(ang), cz, "b");
CL_g_legend(gca(), ["cx", "cz"]);

// Aerodynamic coefficients vector - two sides - drag + lift
aero_vec = CL_mod_aeroPanelCoefV(vel_wind,  normal, temp, temp_p, m_mol_mass, ratio_spec, alpha, 2, "acv");

scf();
plot(CL_rad2deg(ang), aero_vec(1,:), "r");
plot(CL_rad2deg(ang), aero_vec(2,:), "g");
plot(CL_rad2deg(ang), aero_vec(3,:), "b");
CL_g_legend(gca(), ["x", "y", "z"]);
