drugDeliveryBuongiornoPimpleFoam

This is a solver for drug delivery and unsteady forced convection heat transfer of nanofluid using the Buongiorno model to consider nanoparticle distribution written based on foam-extend-4.1.

Mathematical Relationships

$$ \nabla . U = 0 $$

$$ {dU \over dt} + {(U . \nabla) U} = - {1 \over \rho{nf}} \nabla p + \nu{nf} \nabla . {\nabla U} $$

$$ {dT \over dt} + {U . \nabla T} = \alpha_{nf} {\nabla}^2 T $$

$$ {d \phi \over dt} + {U . \nabla \phi} = Db {\nabla}^2 \phi + {DT \over T} {\nabla}^2 T $$

$$ DB = {{kB T} \over {3 \pi \muf \ d{np}}} $$

$$ DT = 0.26 {{\kappaf} \over {2 \kappaf + \kappanp}} {\muf \over \rhof} \phi $$

$$ \rho{nf} = \rho{np} \phi + \rho_f (1 - \phi) $$

$$ C{p,nf} = {{ \rho{np} C{p,np} \phi + \rhof C{p,f} (1 - \phi)} \over \rho{nf}} $$

$$ {\kappa{nf} \over \kappaf} = { {2 \kappaf + \kappa{np} + 2 \phi ( \kappa{np} - \kappaf)} \over {2 \kappaf + \kappa{np}- \phi ( \kappa{np}- \kappaf)} } $$

$$ {\mu{nf} \over \muf} = {1 \over (1 - \phi)^{2.5}} $$

Which $U$, $p$, $T$, and $\phi$ are velocity vector, pressure, temperature, and nanoparticle concentration, respectively. And $\rho$, $Cp$, $\kappa$, $\mu$, $\nu$, and $\alpha$ are density, specific heat capacity, thermal conductivity, dynamic viscosity, kinematic viscosity, and thermal diffusivity, respectively. Also, subscription $f$, $np$, and $nf$ depict fluid, nanoparticle, and nanofluid, respectively. Moreover, $DB$, $DT$m and $d{np}$ are Brownian diffusion, thermophoresis diffusion, and nanoparticle diameter, respectively.
