The results establish the versatility of electrospinning as a scaffold fabricating technology that can produce scaffolds with the required porous properties by properly understanding the processing parameters. 1 is an example of how a map can be produced for the control and tailoring of scaffold structures that can be reproducibly manufactured. 3 properties, scaffolds S-1, S-3, S-4, and S-7 were chosen as they represent low (S-1 and S-3), medium (S-4), and high (S-7) porosities. In the case of scaffolds S-1 and S-2, the porosity is similar, but the pore sizes are different, allowing for a comparison for scaffolds with similar porosity and different pore sizes.
In the case of continuum models, studies have considered multiphase models with volume averaging of the variables over the volume in each phase (Lemon and King, 2007). These multiphase models include the solid phase of the porous scaffold, the fluid phase (culture medium), and sometimes the solid-cell phase. The first factor that will affect the transport of nutrients and cells is the decreased fluid flow through the scaffold as cells attach to it and proliferate. In the case of scaffoldbased tissue engineering solutions, both the scaffold and the attached cells are generally considered as a porous medium, and the flow of the culture medium (with the nutrients and suspended cells) through the porous medium can be described by a number of mathematical equations.
