A Full-Cycle 3 Dimensional Numerical Simulation of a Direct Injection Diesel Engine

In the present work, multidimensional modeling of open-cycle process of OM355 engine was developed. Calculations for computational mesh were carried out. The results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. Results included pressure, temperature, emissi...

Direct statistical simulation of out-of-equilibrium jets.

We present direct statistical simulation of jet formation on a β plane, solving for the statistics of a fluid flow via an expansion in cumulants. Here we compare an expansion truncated at second order (CE2) to statistics accumulated by direct numerical simulations. We show that, for jets near equilibrium, CE2 is capable of reproducing the jet structure (although some differences remain in the s...

Direct Statistical Simulation of Timing Properties in Sequential Circuits

Accurate timing analysis of digital integrated circuits is becoming harder to achieve with current and future CMOS technologies. The shrinking feature sizes lead to increasingly important local process variations (PV), making existing methods like corner-based static timing analysis (STA) yield overly pessimistic results. In this paper we propose a general purpose statistical circuit simulator ...

Dimension reduction in statistical simulation of digital circuits

Statistical analysis tasks are increasingly encountered in the design of digital circuits that implement complex Boolean functions. Examples include analyzing the impact of soft errors, estimating power consumption, and stochastic computation. Common simulation techniques such as quasiMonte Carlo simulation often converge too slowly for large circuits with many inputs, i.e., many dimensions. We...
