The application of solid propulsion has a wide range of advantages and disadvantages in space exploration and defence systems. The rocket performance is mainly described by the specific Impulse (Isp) produced by the propulsion system. The specific impulse has a very high significance in the design of a rocket and missile system. The paper is aimed to develop a numerical model for the prediction of specific impulse in a dual bell nozzle. The dual bell nozzle is a mostly used rocket that is used wide range in the industry of space exploration. The CFD simulation has been performed on the nozzle at different altitudes such as at the sea level, 4 Km, 8 Km, 12 Km, 16 Km, 20 Km, and vacuum. The simulation is performed with an inlet pressure of 7.34 MPa and inlet Temperature of 3410 K. and has a mass flow rate of the combusted gasses of 5.96 Kg/s. The simulation is performed that to observe the specific impulse of the solid motor rocket at different altitudes."> <meta name="citation_fulltext_html_url"

is a widely used propulsion system in the industry of aerospace. The application of solid propulsion has a wide range of advantages and disadvantages in space exploration and defence systems. The rocket performance is mainly described by the specific Impulse (I<sub>sp</sub>) produced by the propulsion system. The specific impulse has a very high significance in the design of a rocket and missile system. The paper is aimed to develop a numerical model for the prediction of specific impulse in a dual bell nozzle. The dual bell nozzle is a mostly used rocket that is used wide range in the industry of space exploration. The CFD simulation has been performed on the nozzle at different altitudes such as at the sea level, 4 Km, 8 Km, 12 Km, 16 Km, 20 Km, and vacuum. The simulation is performed with an inlet pressure of 7.34 MPa and inlet Temperature of 3410 K. and has a mass flow rate of the combusted gasses of 5.96 Kg/s. The simulation is performed that to observe the specific impulse of the solid motor rocket at different altitudes.</p> </p> <p class="mb-1 font-size-3 text-muted"> <b>Published Date: </b> 2023-01-17; <b>Received Date: </b>2022-10-09</p> <nav class="nav a-pl-0"> <a href="https://www.longdom.org/open-access/prediction-of-solid-rocket-motor-performance-in-a-pintledual-bell-nozzle-using-computational-fluid-dynamics-99100.html" title="Click here" class="nav-link text-danger"><img src="/assets/img/html.svg" alt="html" height="26"></a> <a href="https://www.longdom.org/open-access/prediction-of-solid-rocket-motor-performance-in-a-pintledual-bell-nozzle-using-computational-fluid-dynamics.pdf" title="Click here" class="nav-link text-success"><img src="/assets/img/PDF_32.png" alt="pdf" height="26"></a> </nav> <div class="nav social-icons"> <a class="nav-link w-auto">Share this article</a> <a title="Click here" target="_blank" href="https://www.facebook.com/sharer.php?u=https://www.longdom.org/abstract/prediction-of-solid-rocket-motor-performance-in-a-pintledual-bell-nozzle-using-computational-fluid-dynamics-99100.html" rel="noopener"><i class="fab fa-facebook-f"></i></a> <a class="nav-link" title="Click here" target="_blank" href="https://twitter.com/share?url=https://www.longdom.org/abstract/prediction-of-solid-rocket-motor-performance-in-a-pintledual-bell-nozzle-using-computational-fluid-dynamics-99100.html" rel="noopener"><i class="fab fa-twitter"></i></a> <a class="nav-link" title="Click here" target="_blank" href="https://www.linkedin.com/shareArticle?mini=true&url=https://www.longdom.org/abstract/prediction-of-solid-rocket-motor-performance-in-a-pintledual-bell-nozzle-using-computational-fluid-dynamics-99100.html" rel="noopener"><i class="fab fa-linkedin-in"></i></a> <a class="nav-link" title="Click here" target="_blank" href="https://plus.google.com/share?url=https://www.longdom.org/abstract/prediction-of-solid-rocket-motor-performance-in-a-pintledual-bell-nozzle-using-computational-fluid-dynamics-99100.html" rel="noopener"><i class="fab fa-google-plus-g"></i></a> </div> </div> </div> </div> </section> <footer class="bg-blue-grey-900 py-3"> <div class="container"> <div class="row"> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">Content Links</h4> <ul class="list-unstyled footer-links font-size-3"> <li><a class="" href="https://www.longdom.org/online-tools.html" title="Click here">Tools</a> </li> <li><a class="" href="https://www.longdom.org/feedback.html" title="Click here">Feedback</a></li> <li><a class="" href="https://www.longdom.org/careers.html" title="Click here">Careers</a></li> <li><a class="" href="https://www.longdom.org/privacy-policy.html" title="Click here">Privacy Policy</a></li> <li><a class="" href="https://www.longdom.org/terms-conditions.html" title="Click here">Terms & Conditions</a></li> <li><a class="" href="https://www.longdom.org/authors-reviewers-editors.html" title="Click here">Authors, Reviewers & Editors</a></li> </ul> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">Contact Longdom</h4> <p>Longdom Group SA<br> Avenue Roger Vandendriessche,<br> 18, 1150 Brussels, Belgium<br> Phone: +442038085340 <br><strong>Email:</strong> <a href="mailto:info@longdom.org" class="white" title="Click here">info@longdom.org</a></p> </div> <div class="col-12 col-sm-4"> <h4 class="white font-size-4 fweight-400 border-bottom-1 pb-2">Connect</h4> <nav class="nav nav-pills social-icons-footer flex-column a-pl-0"> <a href="https://www.facebook.com/longdompublisher" title="Click here" target="_blank" class="nav-link bg-facebook-hover"><i class="fab fa-facebook-f bg-facebook"></i> Facebook</a> <a href="https://www.linkedin.com/company/longdom-publishing-sl/" title="Click here" target="_blank" class="nav-link bg-linkedin-hover"><i class="fab fa-linkedin-in bg-linkedin"></i> Linkedin</a> <a href="https://twitter.com/LongdomP" title="Click here" target="_blank" class="nav-link bg-twitter-hover"><i class="fab fa-twitter bg-twitter"></i> Twitter</a> <a href="https://www.instagram.com/longdom_publisher/" title="Click here" target="_blank" class="nav-link bg-instagram-hover"><i class="fab fa-instagram bg-instagram"></i> Instagram</a> </nav> </div> </div> <div class="row text-center"> <div class="col"> <p>Copyright © 2024 <a href="https://www.longdom.org/" title="Click here" class="white">Longdom Publishing</a>.</p> </div> </div> </div> </footer>  <a href="#0" class="cd-top js-cd-top">Top</a>   <script defer src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script defer src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script> <script defer src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>  <script> jQuery(function($) { $(window).scroll(function fix_element() { $('#target').css( $(window).scrollTop() > 100 ?
