## Abstract

We present results of several numerical simulations of two dimensional advective flows which include cooling processes. We show that the computed light curve is similar to the $\\chi$ state in GRS 1915+105. The power density spectrum (PDS) also shows presence of QPOs near the break frequency.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
