On the width of cold fronts in clusters of galaxies due to conduction

open access: yes, 2007
We consider the impact of thermal conduction in clusters of galaxies on the (unmagnetized) interface between a cold gaseous cloud and a hotter gas flowing over the cloud (the so-called cold front).

Two-Dimensional Hydrodynamic Models of Super Star Clusters with a Positive Star Formation Feedback

open access: yes, 2008
Using the hydrodynamic code ZEUS, we perform 2D simulations to determine the fate of the gas ejected by massive stars within super star clusters. It turns out that the outcome depends mainly on the mass and radius of the cluster.

Magnetothermodynamics: Measurements Of The Thermodynamic Properties In A Relaxed Magnetohydrodynamic Plasma [PDF]

open access: yes, 2018
We have explored the thermodynamics of compressed magnetized plasmas in laboratory experiments and we call these studies ‘magnetothermodynamics’. The experiments are carried out in the Swarthmore Spheromak eXperiment device.

Predicted Gas Properties in the Shock Layer Ahead of Capsule-Type Vehicles at Angles of Attack [PDF]

open access: yes
A method for determining shock-wave shapes, stagnation-point location, and flow-field properties for spherically blunt bodies at angle of attack was developed. The method is applicable to perfect gas flows and equilibrium flow of real gases.

Asymptotic models of meridional flows in thin viscous accretion disks

open access: yes, 2002
We present the results of numerical integrations yielding the structure of and meridional flow in axisymmetric thin viscous accretion disk models.

Numerical and Experimental Study on Deicing of Wind Turbine Blades by Electric Heating Under Complex Flow Field

open access: yesMachines
Wind turbine blades are prone to icing in cold environments, which leads to decreased aerodynamic performance, increased power loss, and even endangers the safe and stable operation of wind turbines.

Effect of LN2 injection station location on the drive fan power and LN2 requirements of a cryogenic wind tunnel [PDF]

open access: yes
A theoretical analysis comparing the fan power and coolant (LN2) flow rates resulting from injection of the LN2 either upstream or downstream of the drive fan of a closed circuit transonic cryogenic tunnel is presented.

Stagnation-point heat-transfer rate predictions at aeroassist flight conditions [PDF]

open access: yes
The results are presented for the stagnation-point heat-transfer rates used in the design process of the Aeroassist Flight Experiment (AFE) vehicle over its entire aeropass trajectory.

Finite difference solution to the three-dimensional, incompressible thermal energy boundary-layer equation [PDF]

open access: yes
An implicit numerical method has been adopted for the solution to the three-dimensional, energy boundary-layer equation. The energy equation is written in terms of a dimensionless temperature function, the relative stagnation-enthalpy difference, and ...
