The cold junctions of thermal piles are put outside the cap to make it exactly at the room temperature, thus the device is very easy to calibrate and more accurate. (4) The chamber is filled with another kind of gas such as Xe or Ar to avoid the oxidizing effect produced by the commercial ones with carbon dioxide or air, and then the reliability as well as the life cycle of the heater can be increased. (5) By the results of simulation, one can see the traditional rectangular chamber can be replaced by a hemi-cylindrical one to extend both the operation range and sensitivity of the thermal convection accelerometer.

There are four known approaches used to solve Navier-Stokes equation: - solution of Reynolds – averaged Navier-Stokes equations (RANS) ; - direct numerical simulation (DNS), solution of Navier-Stokes unsteady-state equations without closing relations; - large eddy simulation (LES), which is based on Navier-Stokes unsteady-state equations performed with parameterization of sub grid scale eddies; - method called DES, which is a combinations of two methods : LES – in the zone of separated flow and RANS – in the zone of “smooth flow”.
