Chestermiller's latest activity
-
Chestermiller replied to the thread Construction of a model of a hydraulic damper.Is this an existing physical piece of equipment that you can perform experiments on, or is it a schematic of a damping concept that you... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.Are you familiar with lubrication flow analysis? Do you know how to solve the problem of laminar flow between two infinite parallel plates? -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.I would first derive and solve the equations for the fluid dynamics of the system. Do you know how to solve axial annular laminar flow... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.The viscous damper I described in post #2 does not require CFD analysis to quantify its behavior. It can solved analytically for the... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.I'm thinking of a cylinder with a piston in which the clearance between the piston and the cylinder wall is finite. The piston is long... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.Damping is often approximated using an ideal dashpot. Is that what you are searching for: an approximate equation for the dashpot... -
Chestermiller replied to the thread Need help with pressurized air.100% RH means that the partial pressure of the water in the tire is equal to the equilibrium vapor pressure of water at the air... -
Chestermiller replied to the thread Undergrad Difference calculating enthalpy change by using thermodynamic table A-17 vs. A-2 with integration.The table in the first method used integration with respect to temperature also. It would seem to be a matter of the difference in the... -
Chestermiller replied to the thread Spring aproximation.Yes, neglecting dissipation factors such as air drag. -
Chestermiller replied to the thread Undergrad Is Callen right in claiming dQ=TdS for all quasi-static processes?.A quasi-static path is considered to represent a continuous sequence of thermodynamic equilibrium states. -
Chestermiller replied to the thread Undergrad Joule-Thomson Expansion.Who says that in thermodynamics, we study gases that are in thermodynamics equilibrium? The states of the gas in irreversible processes... -
Chestermiller reacted to Andrew Mason's post in the thread Undergrad Is Callen right in claiming dQ=TdS for all quasi-static processes? with
Like.
$$\Delta S=\int dS=\int dQ/T$$ is the definition of change in entropy, where dQ is the infinitesimal heat flow over a reversible path... -
Chestermiller replied to the thread Old man, new member.Was it also called the Missouri School of Mines, or is that something different? -
Chestermiller replied to the thread Graduate Strain Tensor Based on Clifford Algebra.For large deformations, the definition of the strain tensor is not unique. There are many tensorial forms at large deformation that... -
Chestermiller replied to the thread Rubber tyre “melting” inside, turned to deadly goo. Why?.Thermal chemical decomposition of the rubber.
