Detailed Description

This source condition sets the values of the pressure to that of the carrier plus an amount caused by the effect of the surface tension on a spherical droplet or bubble.

Note that for now, the surface tension is an input parameter. This is likely to change as more surface-tension-dependent models are introduced and it becomes necessary to centralise the specification of the surface tension modelling. For now, this serves as a proof of concept that the pressure of the particles can differ from that of the carrier.

Usage
Property Description Required? Default
sigma The surface tension coefficient yes

Example specification: 

    <LagrangianModelName>
    {
        type            LaplacePressure;
        sigma           0.07 [N/m];
    }
