Appearance of the experimental stand: 1 – halogen lamp 0.5 kW; 2 – focusing mirror; 3 – reactor chamber; 4 – analytical balances; 5 – thermal imager PI 1M; 6 – gas analyzer TEST-1.

The component composition of the generated gas is recorded by the TEST-1 gas analyzer. The outlet path contains a condensate collector and a filtration system consisting of a PTFE filter and a carbon filter.

The temperature trend during the process is recorded by a PI 1M thermal imager. Processing occurs using licensed software supplied on a flash drive included with the device. Mass yield is measured using Vibra scales. Using the LabView software package, automatic measurement and data transfer to a computer is realized in real-time mode.

To maintain the specified temperature of the suspension samples, a cryostat CRIO-VIS-T-06-01 from TERMEX was used (temperature range from -30 to +100 °C, ensured by using a coolant - a mixture of propylene glycol and water in a ratio of 50/50, temperature deviation in working capacity ±0.01 °С).

To implement the movement of liquid in the pipeline (8 mm), a BT100-1F peristaltic pump was used (capacity 0.0002 - 600 ml/min, rotation speed range 0.1 - 100 rpm).

Temperature control was carried out using two temperature meter-controllers (2ТРМ1) with thermoelectric converters ХК (measurement range 0–1200 °С.

To maintain the homogeneity of the suspension, a DC-600RM overhead stirrer was placed in the tank. The reservoir is filled with the test sample of the fuel mixture (volume ≈ 1.5 liters), after which the mixing device is turned on at a given rotation speed ≈ 0–1500 rpm.

The heat exchanger is an aluminum tube with a diameter of 6 mm and a length of 500 mm, bent in the form of a round spiral, designed to increase heat exchange between two media.

The purpose of the experiments is to study the interaction of the first microgel particle with surfaces, as well as the interaction of the second microgel particle with the first. To form microgel particles, a system for generating a dual flow of liquids has been developed. The resulting flow of microgel particles is formed as a result of the interaction in the air of a microdroplet flow of polymer with a microjet flow of crosslinker.

Appearance of the experimental stand: 1 – syringe pump for supplying a polymer solution, 2 – syringe pump for supplying a crosslinker solution, 3 – frame for attaching a needle, 4 – piezo actuator, 5 – syringe needle, 6 – high-speed video camera, 7 – personal computer, 8 – power supply, 9 – signal supply and amplification system, 10 – lighting system, 11 – hose for supplying a polymer solution, 12 – hose for supplying a crosslinker solution, 13 – solid wall; 14 – container for collecting waste liquid; 15 – linear coordinate device

The collision of gel microdroplets with surfaces is recorded using a high-grade Phantom Miro M310 video camera. The high-quality camera is used with a Nikon 200mm FX NIKKOR f/5.6 lens. The main parameters of the processes of interaction of microgel particles with the surface are recorded: Initial diameter of particles D0, speed of movement of microparticles U0, diameter of liquid bridges δ, m; diameter of spreading (deformation) of particles D, m, h – height of the spreading (deformable) particle. The test compounds are supplied using SPLab 02 syringe pumps. The flow speed varies in the range of 0.1–2 m/s due to changes in the pump flow rate.

The crushing of the sodium alginate solution flow is carried out using a multilayer piezoelectric actuator.

The impact of liquid droplets with a solid surface is recorded using a high-grade video camera Phantom Miro M310 and Miro C110. The high-quality camera is used complete with a Sigma 200 mm and 105 mm lens, respectively. The main parameters of the processes of interaction between drops and particles are recorded: drop diameter (D0), drop speed (U0), drop spreading diameter after impact with the surface (D). Variation of droplet size in the range of 0.2–1.0 mm when using replaceable nozzles: G17, G21, G25, G30. The supply of drops of the studied compositions is carried out using a LongerPump BT100-1F peristaltic pump. The droplet speed varies in the range of 0.1–10.0 m/s by changing the height of the nozzle relative to the particle.

This research pilot stand is an installation designed to study the operating features of turbojet engines on smaller copies with an electric drive with the possibility of changing the engine sample to a similar one with modified characteristics. Each sample engine is built into a rugged metal frame that holds it securely while allowing the thrust produced by the engine to be accurately measured. The stand supports measurements of many characteristics of flow temperature and air mass flow. The complex includes both the measuring stand itself and two engine modules of the same type with different thrust characteristics and geometric dimensions, for the possibility of cross-testing. The complex consists of two independent modules: a power unit with engines and a software-measuring complex with sensors and software for testing and measuring engines installed on a firing stand.
