Application of the Direct Simulation Monte Carlo Method to Modeling of Microfluidics

Sharipov F., Universidade Federal do Parana, BR

For mathematical modeling of microfluidics it is necessary to calculate a rarefied gas flow through micropumps, microvalves and other elements with high accuracy. Since the size of microfluidics is close to the molecular mean free [...]

Data on the Slip Coefficients

Sharipov F., Universidade Federal do Parana, BR

For mathematical modeling of micro fluidics it is necessary to calculate a rarefied gas ow through micropumps, microvalves and other elements with a high accuracy. Since the size of micro fluidics is close to the [...]

Application of the Gaseous Cross Phenomena to Microfluidics

Sharipov F., Universidade Federal do Parana, BR

Since the size of micro fluidics is very small the gas owing through micropumps, microvalves etc. can not be considered as a continuous medium but its rarefacation must be taken into account. The rarefied gas [...]

Non-Isothermal Gas Flow Through Rectangular Microchannels

Sharipov F., Universidade Federal do Parana, BR

The mass flow rate of a rarefied gas through a long rectangular channel caused by both pressure and temperature differences has been calculated applying the S model kinetic equation. The calculations have been carried out [...]

Computational Two-Dimensional Finite-Element Analysis of Flow Behavior Inside Microfluidic Amplifiers

Simões E.W., Furlan R., Zemel J.N., Escola Politecnica da Universidade de Sao Paulo, BR

Two-dimensional finite-element analysis was conducted using the commercial ANSYS (FLOTRAN) package to investigate nitrogen flow inside of two types of microfluidic amplifiers (wall attachment and jet deflection). Our simulations demonstrate that for supply pressures higher [...]
