The purpose of this study is to analyze structural properties of biomass materials, namely corn stover. The structural properties of the biomass corn stover are examined at macro and fiber levels by performing a series of tests including three-point bending and tensile strength. Results of the stated tests are statistically analyzed. The goal of this analysis is to test the strength under loading from various directions to gather a full understanding of the structural properties of corn stalk fibers. Tests are performed using universal testing machines (UTMs). The results of these studies will be used to compile a database of the structural properties of biomass. These properties have the potential to be used in finite element computer simulations for structural analysis and bulk solid flows. The bulk fluid motion of the pulverized/chopped biomass can be simulated in storage and transportation equipment, including auguring screws and pneumatic conveyance systems, as well as devices for feeding biomass feedstocks in biorefineries. Traditional biochemical and thermochemical reactors operate as batch systems because of the difficulty of feeding the biomass feedstock in a continuous manner. Having a clearer background about the structural and rheological properties of biomass feedstock will help simulate and design the bulk-solid flows within storage bins and conveyance systems.

Flow parameters of chopped biomass, namely corn stover, are analyzed applying material testing techniques. The bulk fluid motion of the chopped biomass corn stover is examined using a custom made direct shear cell and a universal testing machine. The goal of this analysis is to test the bulk solid shear stress, internal friction, internal angle of friction and cohesion. The results of the stated tests are statistically analyzed and compared with literature. The measured properties of the biomass have the potential to be used in computer simulations for bulk solid flow analysis. The bulk fluid motion of the pulverized/chopped biomass can be simulated in storage and transportation equipment, including auguring screws and pneumatic conveyance systems, as well as devices for feeding biomass into thermochemical and biochemical reactors. Traditional biochemical and thermochemical reactors operate as batch systems because of the difficulty of feeding the biomass feedstock in a continuous manner. Having a clearer background about the structural and rheological properties of biomass feedstock will help simulate bulk-solid flows computationally and design efficient storage and continuous feeding systems.

The purpose of this study is to analyze structural material properties of biomass materials, namely corn stover. The microstructure of the biomass is examined by using a nano-hardness testing machine (NANOVEA®). The goal of this analysis is to test the hardness and elasticity of individual fibers using nanoindentation and to develop testing techniques to perform this task. The results of the stated tests are statistically analyzed. The measured structural properties of the biomass have the potential to be used in computer simulations for structural analysis and bulk solid flows. The bulk fluid motion of the pulverized/chopped biomass can be simulated in storage and transportation equipment, including auguring screws and pneumatic conveyance systems, as well as devices for feeding biomass feedstocks in biorefineries. Traditional biochemical and thermochemical reactors operate as batch systems because of the difficulty of feeding the biomass feedstock in a continuous manner. Having a clearer background about the structural and rheological properties of biomass feedstock will help simulate and design the bulk-solid flows within storage bins and conveyance systems.
