Fluid Mechanics and Heat Transfer Library

The ETBX Fluid Mechanics And Heat Transfer library contains modules concerned with fluid and thermal flow.

Fluid Flow Rate and Pressure Drop - Compute the flow rate and pressure drop due to fluid flow in a pipe. The pipe cross-section can be circular, annular or rectangular. Laminar or turbulent flow of an incompressible fluid (gas or liquid) can be computed.

Convection Heat Transfer Coefficient for Pipe Flow - Computes the heat transfer coefficient for fluid flow in a pipe. The pipe cross-section can be circular, annular, or rectangular. Heat transfer due to laminar or turbulent flow of an incompressible fluid (gas or liquid) can be computed.

Water Hammer - Computes the magnitude of the pressure pulse generated due to the closing of a valve in a flow line.

Turned Flow - Computes the force generated due to turning of fluid in a short duct.

Converging-Diverging Nozzle Flow - Calculates the maximum gas flow rate and flow regime in a converging-diverging nozzle. This module can also be applied to compute the maximum allowable mass flow rate of a gas through a given cross-section.

Convection Heat Transfer Coefficient for External Flow - Computes convection heat transfer coefficients for incompressible fluid flow across flat plates, spheres, cylinders, and arrays of cylinders. Heat transfer coefficients for both laminar or turbulent flow of an incompressible fluid (gas or liquid) can be computed.

Heat Conduction - Calculates heat fluxes, temperatures, and effective thermal resistance through slabs, long cylinders, and spheres under steady state conditions. This module can be used to compute heat transfer for multiple layers of flat plates, cylinders, and spheres. Heat conduction for temperature and heat flux boundary conditions can be analyzed.

Droplet Evaporation - Computes one-dimentional transport of a particle/droplet by a carrier gas. Mass, momentum, and energy exchange between the particle / droplet and carrier gas is included. The module can be applied to estimate the terminal velocity and time required to attain terminal velocity in a carrier gas moving at constant velocity. It can also be used to examine the heating or cooling of a particle / droplet in a carrier gas. The evaporation of a droplet in a carrier gas can also be computed.
