Space systems design (spacecraft, satellites, space stations and their equipment)
Optimized Dimension Design of Catalytic Chamber of a 10 N Thruster

Sajjad Davari; Hadiseh Karimaei; Mohammad Reza Salimi; Hassan Naseh

Volume 16, Issue 2 , June 2023, , Pages 55-61

  In this paper, the catalyst bed of a 10 N hydrazine monopropellant thruster was designed. The catalyst bed is including iridium granules, which is used to decompose the hydrazine in monopropellant thruster. Hydrazine must be decomposed almost completely in the catalytic chamber, because it is a carcinogenic ...  Read More

According to this design, a prototype of the thruster will be manufactured. The mentioned thruster has been ...  Read More

Implementation of Linear Hydrodynamic Instability Theory on a Hollow Cone-shaped Liquid Sheet of a Swirl Injector

Hadiseh Karimaei; Ramin Ghorbani; Seyed Mostafa Hoseeinalipour

Volume 11, Issue 4 , March 2019, , Pages 1-10

  In the atomization process, small disturbances grow in liquid jet or sheet and eventually cause to disintegrate it into ligaments and smaller droplets. Concerning to the motion of waves on the liquid sheet surface, the stage of primary breakup is deterministic and can be predicted by instability analyzes. ...  Read More

Microscopic Test of a Swirl Injector by High-speed Photography

Hadiseh Karimaei; Mostafa Hossein Alipour; F Ommi; Ehsan Movahednejad; Reza Sharifzadeh

Volume 10, Issue 4 , March 2018, , Pages 1-7

  A swirl injector is tested to investigate the instability of the liquid sheet emanating from it and determine the main microscopic characteristics of the spray. The injector, which is tested, was already approved by doing the characterization tests (macroscopic). Due to the fact that the PDPA systems ...  Read More

Extraction of a Theoretical Energy-based Model to Estimate Mean Droplet Diameter of the Swirl Injector Spray

Hadiseh Karimaei; seyed mostafa hosseinalipour

Volume 10, Issue 3 , December 2017, , Pages 59-65

  The droplet formation stage of a spray, which enjoys a great diversity in size and droplet velocity, is predictable through a statistical approach. Since the available methods require experimental data such as mean droplet diameter and mean droplet velocity as inputs to estimate the distribution of the ...  Read More
