Numerical Simulations Of An Inductively Coupled Plasma Torch, Samuel Whitmore
Numerical Simulations Of An Inductively Coupled Plasma Torch, Samuel Whitmore
Graduate College Dissertations and Theses
During entry into a planetary atmosphere, a blunt body (e.g. a spacecraft) traveling at hypersonic velocity creates a bow shock in front of it. In the highly energetic post shock environment, the body experiences heat transfer due to convective, chemical, and radiative processes. To protect the payload against this heating, a thermal protection system (TPS) is employed. Because a given propulsion system has a set amount of mass that it can launch to orbit, reducing the amount of mass used for TPS is desirable as this mass is freed up for mission-oriented payload. At the present, uncertainties in the flow …
Segregation Of Particles Of Variable Size And Density In Falling Suspension Droplets, Melissa Kathleen Faletra
Segregation Of Particles Of Variable Size And Density In Falling Suspension Droplets, Melissa Kathleen Faletra
Graduate College Dissertations and Theses
The problem of the falling under gravity suspension droplet was examined for cases where the droplet contains particles with different densities and different sizes. Cases examined include droplets composed of uniform-size particles with two different densities, of uniform-density particles of two different sizes, and of a distribution of particles of different densities. The study was conducted using both simulations based on Oseenlet particle interactions and laboratory experiments. It is observed that when the particles in the suspension droplet have different sizes and densities, an interesting segregation phenomenon occurs in which lighter/smaller particles are transported downward with the droplet and preferentially …
