The China Seismo-Electromagnetic Satellite (CSES-01), in orbit since February 2, 2018, is the first element of an extended constellation of LEO (Low-Earth Orbit) satellites, dedicated to monitoring perturbations of electromagnetic fields, plasma and charged particle fluxes induced by natural sources and artificial emitters in the near-Earth space. The Limadou Collaboration, which is the Italian branch of the aforementioned mission, designed and built one of the nine payloads on board the satellite, i.e. the High-Energy Particle Detector (HEPD-01). HEPD-01 is optimized to detect electrons (3–100 MeV), protons (30–300 MeV), and light nuclei (up to a few hundreds of MeV) with a high energy resolution and a wide angular acceptance. The very good capabilities in particle identification together with the orbit of CSES01 make HEPD-01 well suited for measuring galactic particle fluxes and their solar modulation, and also for space weather purposes. In this work, we present some results obtained with HEPD-01 during the first three years in flight, including the observation of the August 2018 geomagnetic storm and the galactic cosmic-ray hydrogen spectra in the 40–250 MeV range.

A computational study of a supersonic flow in the base region and the nearest wake of a cylindrical body moving at a supersonic speed have been carried out. A mathematical model of high-enthalpy flows is presented. In this case, the "prehistory" of the flow was taken into account, i.e., the configuration of the computational domain was as close as possible to the real one. The use of various turbulence models for calculating flow in the base region and the nearest wake was analyzed. The following turbulence models were considered: 1) the Spalart–Allmaras model; 2) SST model; 3) standard κ–ε model; 4) κ–ε model with compressibility correction; 5) κ–ε RNG (renormalized group) model; 6) κ–ε Realizable model; 7) standard Reynolds Stress (RS) model; 8) RS BSL (Reynolds stress baseline) model. Based on a comparison of the calculation results with experimental data, it is shown that: 1) when calculating the flow in the base region and in the wake of the vehicle, it is very important to take into account the "prehistory" of the flow, i.e., to calculate the flow around the entire vehicle; 2) the best match was obtained using Reynolds Stress models and the κ–ε RNG model
